Fuzzy Controller Optimization in PLC
Piskoř, Dominik ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This diploma thesis deals with the search for optimization methods suitable for fuzzy controller optimization. The next goal of this thesis is the manual design of the Mamdani fuzzy controller, off-line optimization of the designed fuzzy controller, and the testing of the optimized controller by controlling a real system. The real system is a model of the wind tunnel, which is consisted of a fan, a tube, and a small turbine placed on a shaft of a rotary encoder. This rotary encoder is used as a sensor. The last part of this thesis is a comparison of the achieved results with a linear controller, which is optimized according to the given criterion.

Closed loop system identification
Piskoř, Dominik ; Buchta, Luděk (referee) ; Pohl, Lukáš (advisor)
This thesis deals with testing of various modifications of the least-squares method, which reduces the bias in system parameter estimation. The first part of this thesis is focused on the theory and principles of every single method. The second part describes the implementation of identification methods in Matlab and Simulink. The third part is focused on the evaluation of used methods via statistical analysis. This part also contains an identification of electric parameters of the real PMSM motor model.
