Temperature control in bioreactor
Pospíchal, Zbyněk ; Václavek, Pavel (referee) ; Blaha, Petr (advisor)
This thesis deal with improvement behavior of temperature control in bioreactor. It was created model of system. Basic PI controller could solve all problems. After analysis of system were decided to used fuzzy controller. Fuzzy controller in comparison with classic PI controller has better behavior in this application.

Accurate positioning of pneumatic drives
Volf, Marek ; Nevrlý, Josef (referee) ; Marada, Tomáš (advisor)
Thesis starts with brief overview of the present role of pneumatic actuators. Further research is carried out in modelling and control of pneumatic actuators. A basic overview of thermodynamic laws is presented. These laws are used to assemble a mathematical model of the pneumatic drive. Subsequently the identification of model parameters is shown. A controller is propřed using fuzzy PID algorithms. Results are compared with the conventional PID controller.

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.

Metody fuzzy řízení
Valach, Jiří
This thesis deals with fuzzy regulation. The theoretical part describes fuzzy logic, fuzzy controllers, fuzzy expert systems and Fuzzy Logic Controller in Matlab Simulink software. The practical part contains a set of typical regulated systems in Matlab Simulink software. The systems are regulated by selected fuzzy controllers in comparison with the classical PID controller.
