Laboratory tasks for ball on an inclined plane
Řezáč, Martin ; Graf, Miroslav (referee) ; Blaha, Petr (advisor)
The thesis deals with the identification and control of dynamic systems using LabVIEW graphical programming environment. Cascade form of control with PI and PD controllers has been used for regulation and designed in Matlab. These controllers were then tested on real product. Laboratory exercises with model solutions are also included.

DC/AC inverter with digital control
Štaffa, Jan ; Pazdera, Ivo (referee) ; Minárik, Vladimír (advisor)
This work is focused on single phase inverters, which are used for the conversion of the direct current to the alternating current and are nowdays used especially in systems of back-up power supply. The specific aim of this work is implementation of design hight power circuit of inverter include calculation of control algorithm. It describes the complete solution of power circuit. Next step is a analysis of problems concerning the digital control with help of signal processor which is used for solution of regulator structure. Check of the design and checkout of control algorithm is made in the form of simulation in the MATLAB Simulink. Debugged program algorithm is subsequently implemented into the signal microprocessor. The work results rate estimation functionality of inverter and solution of control algorithm.

Automatic tuning of the DC motor controller
Tran, Adam ; Brablc, Martin (referee) ; Najman, Jan (advisor)
Diploma thesis deals with designing of algorithmus for automatic controller tunning for DC motors. Automatic tuning function consist of system identification and controller parametrization. Cascade control loop was chosen for its robustness and proper DC motor control. For electric system identification of DC motor was used recursive method of instrumental variables, because of noisy signal from current transducer. In the case of identification mechanical system, there were used least sqares method. According to identified parameters, current controller was parametrized by optimum module and revolution controller according symetrcal optimum.
