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

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.

<p>The purpose of this thesis is to construct a"Program Address Generator"(PAG) to a 24-bit Harvard type, RISC DSP processor using the VHDL language. The PAG is a part of the program control unit, and should consist of the following units: </p><p>A system stack for storing jump and loop information. A program counter, a status register, a stack pointer, an operating mode register and two registers called loop address and loop counter register, to support hardware loops. </p><p>The PAG handles the fetch stage of the processor pipeline, and should handle instructions such as the jump, subroutine jump, return from subroutine/interrupt and loop instructions, among others. </p><p>The PAG was successfully designed, and its function verified through extensive tests, where common combinations of ASM instructions were tested. Files for automated testing was created, to support easy testing if only small changes are applied to the PAG.</p>

<p>Continuously throughout the process of developing Engine Control Units (ECU), the ECU and its control functions need to be dimensioned and tested for the engine itself. Since interaction between an ECU and a physical engine is both expensive and inflexible, software models of the engine are often used instead. One such test system, where an ECU interacts with software models, is called Hardware-in-the-Loop (HiL). This thesis describes a model constructed to facilitate implementation on a HiL testbed. </p><p>The model, derived in Matlab/Simulink, is a Cylinder-by-Cylinder Engine Model (CCEM) reconstructing the angle synchronous torque of a diesel engine. To validate the model, it has been parameterised for the DaimlerChrysler engine OM646, a straight turbocharged four cylinder diesel engine, and tested towards measured data from a Mercedes-Benz C220 test vehicle. Due to hardware related problems, validation could only be performed for low engine speeds where the model shows good results. Future work around this theme ought to include further validation of the model as well as implementation on HiL.</p>
