Induction machnine control techniques and models
Vidlák, Michal ; Knobloch, Jan (referee) ; Pazdera, Ivo (advisor)
This diploma thesis deals with the design of the asynchronous mathematical model, and creation its model in MATLAB Simulink. And by creating different types of asynchronous motor control. At the beginning of the work there are theoretical knowledge about transformation of quantities into coordinates, which are needed for creation of mathematical model and further for machine control. Furthermore, control logarithms are created from these transformed quantities, which can be used to control the torque or engine speed. It is a constant magnetic flux control, scalar control, vector control, and ultimately direct torque control. All derived control algorithms have been tested in MATLAB Simulink. Where were simulations of investigated quantities.

Modern Algorithms of AC Servo-drives Control
Hrnčárek, Martin ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
This master thesis deals with the modern algorithms of the asynchronous induction machine and permanent magnet induction machine. It focuses at vector control, direct torque control and input-output feedback linearization. It also describes a library creation and its usages in the Matlab – Simulink environment. The final part of this thesis contains an implementation of chosen algorithms on the DSC Freescale 56F800E family.

Modeling and simulation of EC motor vector control in Simulink environment
Hořava, Jan ; Szabó, István (referee) ; Toman, Jiří (advisor)
The main goal of my work is the electrically commutated motor with the vector control’s application in the environment of Matlab – Simulink. The theoretical preamble of this document is dedicated to the physical construction of the EC motors. The most common methods are described in the following text – namely it is scalar control, direct torque control and vector control. The conclusion of this work includes the description and analyse of the single parts of a created model of concrete EC motor with the vector control, and simulations results’ evaluation.

Synchronous motor speed control
Šatava, Patrik ; Mach, Martin (referee) ; Ondrůšek, Čestmír (advisor)
This bachelor’s thesis deals mainly with methods for control of synchronous motors for use in electrical drives. In the first part of the thesis the generic theory of a synchronous machine is presented. Furthermore, this part also deals with Park’s linear transformation of the synchronous machine’s equations, and the stability of the machine. Subsequently, methods for control of a permanent magnet synchronous motor for use in electrical drives are presented. Two major presented methods include the vector control and the direct torque control. Furthermore, the thesis deals shortly with scalar control, which is, however, used rarely nowadays. The last part of the thesis presents measured data of two permanent magnet synchronous motors, powered by a variable frequency AC drive. The data was measured at no load with use of three control methods – scalar control, vector control in open loop-mode, and vector control in closed-loop mode; and at load with use of two control methods – scalar control, and vector control in closed-loop mode.

The implementation of AC induction motor control algorithms in DSP 56F8xxx
Jenča, Pavol ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
In this bachelor’s thesis a control algorithms for induction motors are solved using the methods PDSFC and DTC. Functional algorithms are developed in C and assembly language and are transferred from Simulink to a digital signal processor series 56F8xxx of Freescale corporation. The thesis describes induction motors, used control methods, control schemes developed in Simulink, control algorithms in C and assembly language for each block of created schemes and comparation of simulated solutions.
