This paper presents an approach for an automated calibration process for electronic control units (ECU) of power split transmissions in agricultural tractors. Today the calibration process is done manually on a prototype tractor by experts. In order to reduce development costs the calibration process is shifted from prototype testing to software modelling. Simultaneous optimization methods are used within the software modelling to calculate new parameters. The simultaneous optimization includes objective evaluation methods to evaluate the tractor behaviour. With the combination of both methods inside the software modelling, the calibration process can be automated. The success of this approach depends on the quality of the software modelling. Therefore the identification of the initial prototype behaviour and the fitting of the tractor software model is done at the beginning. At the end of the automated calibration the validation and fine-tuning of the calculated parameters are done on the real tractor. These steps are condensed to a five step automated calibration process which includes simultaneous optimization and objective evaluation methods in several applications. After the detailed discussion of this automated calibration process one function of the ECU (one transmission component) will be calibrated through this process as example.

This thesis focuses on the study, implementation and improvement of a digital Generator Control Unit (GCU) for a high-speed synchronous brushless generator. The control of variable frequency power system, a preferred candidate in More Electric Aircraft (MEA), becomes a big challenge. Compared with conventional analog GCU, digital GCU is a future trend due to the properties such as easy tuning, modification and no aging. Control approaches adopted in the new GCU design is introduced. It has multiloop structure and model-based characteristics. Sensorless rotor position detection was used to finish Park transformation. DSP+FPGA based controller hardware was developed in the lab. A set of hardware was designed to implement the control algorithms. VHDL-based software was developed for FPGA, which is working as a bridge between DSP and peripheral circuits. C-based software was designed to implement control algorithm inside DSP. A testbed system was developed according to the lab capacity of CPES. The complete load transit responses were tested according to the standard ISO1540 and EN8420. Good match between simulation and experiment has been reached. Compared with benchmark controller, great improvement in both steady state and dynamic performance is realized. A feasibility of using digital GCU in the next generation aircraft has been proved preliminarily. However, the challenge of reliability issues in digital system and software still needs further attention. / Master of Science

Harvest Weed Seed Control (HWSC) concentrates, removes, or destroys weed seeds as they pass through the combine. Seed impact mills are modifications that are mounted directly to the back of a combine and are one way to implement HWSC. Seed impact mills kill weed seeds during harvest, preventing seeds from being added to the soil seedbank. Mills like the Redekop Seed Control Unit (SCU) and the integrated Harrington Seed Destructor (iHSD) could be used in soybean and wheat production in the eastern United States. Understanding the effectiveness and limitations of these mills is important for grower adoption. So, the aim of this research was to evaluate the efficacy of two seed impact mills, the Redekop SCU and the iHSD, in soybean and wheat. The first objective tested general seed kill of problematic species in soybean and wheat and seed kill in adverse conditions, such as high chaff flow rate into the mill and high chaff moisture. Results from objective one indicate that both the Redekop SCU and iHSD killed >98% and >91% of problematic weed seeds in soybean and wheat, respectively. Increases in chaff flow rate and chaff moisture resulted in a decrease in seed kill for specific species depending on the mill. But even at high chaff flow rates, seed kill remained >98% and >77% in soybean and wheat, respectively. At high chaff moisture, seed kill remained >98% and >74% in soybean and wheat, respectively. The second objective evaluated the percentage of weed seeds that bypassed the seed impact mill by exiting the combine in the straw fraction and the percentage of weed seeds that were killed when they entered the seed impact mill during harvest with a commercial combine. Results at field scale indicated that <5% of weed seeds bypassed the seed impact mill by exiting the combine in the straw fraction during harvest in soybean and wheat. Additionally, during a commercial harvest, the seed impact mills killed >99% and >89% of seeds in soybean and wheat, respectively. The third objective monitored population density changes for common ragweed (Ambrosia artemisiifolia) in soybean and Italian ryegrass (Lolium perenne ssp. multiflorum) in wheat following a harvest with a seed impact mill. Results from objective three indicated that in the growing season following a harvest with a seed impact mill, common ragweed density was reduced by 26% and 77% in the spring and fall, respectively, in soybean, and Italian ryegrass density was reduced by 48% in wheat. The fourth objective evaluated Palmer amaranth (Amaranthus palmeri) and its ability to shift its flowering timing in response to HWSC. If weeds flower earlier, they could shatter seeds earlier, and those seeds would bypass HWSC. Through selective breeding, two populations of Palmer amaranth experienced a shift in flowering timing such that the third generations flowered 54.7 and 41.0 days sooner in the greenhouse than the initial generations. In a common garden experiment, the second generations flowered 5.5 and 8.9 days sooner than the initial generations. These results indicate that seed impact mills, like the Redekop SCU and iHSD, can deliver high seed kill rates to a range of weed species at commercial scale in both soybean and wheat. Even in adverse conditions, the mills still killed >74% of seed from tested species. However, weed species can adapt to HWSC selection pressures, resulting in a loss of HWSC efficacy. Overall, this research indicates that seed impact mills are a good tool that growers can implement to reduce the number of weed seeds being returned to the soil seedbank. / Doctor of Philosophy / Herbicide resistance is a growing problem in global crop production systems. Weeds that escape control during the growing season can produce seeds by the time of crop harvest. During harvest, these weed seeds are captured by the combine, separated from the grain, and spread back into the field by the combine. Harvest weed seed control (HWSC) targets these weed seeds as they exit the combine by concentrating, removing, or destroying them. HWSC is a nonchemical weed control method that can be implemented as part of an integrated weed management system. One way to implement HWSC is through the use of seed impact mills, which are aftermarket modifications that can be installed on the back of the combine. These mills process the harvest residue and kill the weed seeds therein. Seed impact mills were initially designed for small grain production systems in Australia, but they have a potential fit in soybean and wheat production systems in the eastern United States as well. The purpose of this research was to evaluate two seed impact mills, the Redekop Seed Control Unit and the integrated Harrington Seed Destructor, for use in soybean and wheat. Stationary mill testing indicated that >98% and >91% of seeds from tested weed species were killed in soybean and wheat, respectively. Additionally, even in adverse conditions, seed kill was >98% for soybean weeds and >74% for wheat weeds. In the field, the results indicated that <5% of seeds were bypassing the mill in the straw fraction and being returned to the field during harvest. Results also indicated that >99% of soybean weed seeds and >89% of wheat weed seeds were killed when they entered the mill during a commercial harvest. Testing the mills in soybean production indicated that common ragweed density was reduced by 26% and 77% in the spring and fall, respectively, in the growing season following the use of a seed impact mill. Likewise, Italian ryegrass density was reduced by 48% following a harvest with a seed impact mill in wheat. The results indicate promise for using seed impact mills in soybean and wheat as a tool to reduce additions to the soil seedbank. However, weeds are known to adapt to management practices, and one way weeds might overcome HWSC is through earlier flowering, potentially leading to weed seeds falling on the ground before harvest and escaping capture by the combine. Through selective breeding, the time to flower for two populations of Palmer amaranth was shortened by 54.7 and 41.0 days in just three generations in the greenhouse, indicating that weeds could potentially adapt to HWSC, making it less effective.

Unified Diagnostic Service (UDS), which is an international and not a company-specific standard, is used in almost all new electronic control units (ECUs) by now. Modern vehicles have a diagnostic interface for off-board diagnostics, which makes it possible to connect a diagnostic tool to the vehicle’s bus system like Controller Area Network (CAN) and Local Interconnect Network (LIN). However, as the most commonly used method, sequential method on the UDS data transmission over LIN does not only result in low reliability and flexibility but also fails to meet the standard for LIN development defined in the latest LIN specification published by the consortium. With standard workflow and application interfaces, this Master Thesis will develop and evaluate a database-based method to build a UDS system over LIN, where all the information for the network is defined in the LIN database, and the protocol properties are realized in a reusable model so that it can be easily reconfigured for the future development of other services. As a result, a new method including a layered-structure LIN protocol model and a LIN database has been successfully designed and implemented. The prototype is built on the device PIC32MX795, and the database can be deployed by the configuration tool to specify the UDS communication schedule. Further, several performance evaluations have been performed. The tests indicate that the system is qualified on the limited hardware platform and the configuration flexibility is proved by different databases. / Unified Diagnostic Service (UDS), som är en internationell och inte en företagsspecifik standard, används nu i nästan alla nya elektroniska styrenheter (ECU). Moderna fordon har ett diagnostiskt gränssnitt för diagnostik utanför kortet, vilket gör det möjligt att ansluta ett diagnostiskt verktyg till fordonets bussystem som Controller Area Network (CAN) och Local Interconnect Network (LIN). Som den mest använda metoden resulterar emellertid sekventiell metod på UDS-dataöverföringen via LIN inte bara i låg tillförlitlighet och flexibilitet utan uppfyller också standarden för LINutveckling som definieras i den senaste LIN-specifikationen publicerad av konsortiet. Med standard arbetsflöde och applikationsgränssnitt kommer denna masteruppsats att utveckla och utvärdera en databas-baserad metod för att bygga ett UDS-system över LIN, där all information för nätverket definieras i LIN-databasen, och protokollegenskaperna realiseras i en återanvändbar modell så att den enkelt kan konfigureras för framtida utveckling av andra tjänster. Som ett resultat har en ny metod som inkluderar en LIN-protokollmodell med skiktstruktur och en LIN-databas framgångsrikt designats och implementerats. Prototypen är byggd på enheten PIC32MX795, och databasen kan konfigureras av verktyget för att ange UDSkommunikationsschema. Vidare har flera prestationsutvärderingar genomförts. Testen indikerar att systemet är kvalificerat på den begränsade hårdvaruplattformen och konfigurationsflexibiliteten bevisas av olika databaser.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper describes a telemetry system developed for the EA-18G Flight Test program. The program requires transmission of a number of data streams, in IRIG-106 Chapter 4 PCM, Chapter 8 Mux-All 1553, Ethernet, and Fibre Channel formats. The initial requested data rate was in excess of 30 Mbits/sec. The telemetry system must operate at a range up to about 120 miles, at several test ranges, and with several different aircraft maneuvering configurations. To achieve these requirements, the Flight Test Instrumentation group at Boeing Integrated Defense Systems in Saint Louis, developed a telemetry system in conjunction with industry partners and test range customers. The system transmits two telemetry streams with a total aggregate rate on the order of 20 Mbits/sec. Each telemetry stream consists of up to four PCM streams, combined in a Teletronics Technology Corporation (TTC) Miniature Adaptable Real-Time Multiplexer Unit (MARM) data combiner. It uses Nova Engineering multi-mode transmitters capable of transmitting PCM-FM or Shaped Offset Quadrature Phase Shift Keying (SOQPSK). The transmitter also provides Turbo-Product Code (TPC) Forward Error Correction (FEC) to enhance range and improve link performance. Data collection units purchased from outside vendors or developed by Saint Louis Flight Test Instrumentation, translate Ethernet and Fibre Channel information into traditional PCM streams. A Boeing Flight Test Instrumentation developed control system provides flexible selection of streams to be combined into each telemetry stream, and functional control of antenna selection and transmitter operation.
