Software for Laboratory stand with inverters and motors
Smolák, Martin ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
This bachelor‘s thesis focuses on control firmware for two microprocessors and visualization software of laboratory tasks on the computer. The first of the microprocessor controls a DC motor with permanent magnets and the second one an induction motor. The thesis first describes the hardware of the stand, the principle of AC motors control, Clark‘s and Park‘s transformation, description of firmware for DC and induction motor. Further there is described the visualization environment which serves students for controlling the stand and for calculation of the current regulator using the method of optimal module.

Digitaly controlled inverter for induction motor
Dráb, Dominik ; Klíma, Bohumil (referee) ; Knobloch, Jan (advisor)
This thesis deals with the design of control unit of frequency converter for asynchronous motor, that is part of the laboratory stand. The work contains basic description of asynchronous machine and explanation of operation and design of frequency converters. Furthermore, the work explains the most commonly used methods for control of electrical drives with asynchronous motor. The following chapter describes the design of control module with microprocessor from Freescale. The work also deals with the creation of software for microprocessor. Additionally, the graphical user interface was designed for controlling the stand using a computer. The final chapter of thesis describes measurement of the induction motor.
