This paper deals with the modeling of asynchronous motor. Ccomparing the simulation date to reality. And attempts to find an algorithm for calculating the mechanical torque assist state estimation engine.

This thesis has its main subject pointed on possibilities of exploiting reconfigurable digital systems on FPGA basis in mixed signal applications. Description of reconfigurable and adaptive systems in general and summary of known architectures is presented in first part of this work. Next, possibilities of exploiting configurability of FPGAs in conjunction with XADC digital to analog converter are examined. These converters are provided in 7-series FPGAs and Zynq-7000 systems from Xilinx. Concept of exploiting XADC for inductance measurements is presented as alternative to existing solution - LDC1000 integrated circuit provided by Texas Instruments. Such system utilizing FPGA and XADC would come with a lot of benefits: better system integration, better signal processing options, possibility of constructing adaptive system with numerous sensory elements and last but not least, lower system cost. Advantages and disadvantages of such approach are analyzed in the very final part of this work and possible options for extension of this work are presented.

This master’s thesis is dealing with possibilities of measurement of inductance by using of accurate capacitance bridge AH 2500E. In metrology there are no appropriate devices available for accurate measurement of inductance. It can be realized by four methods. The newest one is based on T elements, it is not used for this purpose yet and it is practically investigated in CMI Brno. For its introduction to practice it is neccessary to complete computer simulations and analysis of influences affecting measurement. It is also inevitable to examine repeatability of measurement, define methodology of measurement and potential corrections of measured values.

This thesis deals with the possibility of using the finite elements method for the analysing of synchronous permanent magnets machines. The aim of this work is to discuss the possibility of the machine design more effectively with using the finite elements method and Maxwell software for the simulations. On the created parametric model, simulations were performed according to master thesis assignment. The aim of this work is to determine induced voltage, iron losses, machine inductances and make a permanent magnets demagnetization analysis. From simulations results the machine efficiency is calculated. The parametric model was used for the optimization of selected parameters. From results of optimization new dimensions of permanent magnets was obtained. Machine efficiency was increased by new permanent magnet material and optimized design.
