Permanent magnet synchronous motor control with respect to simplicity of the realization
Vybíral, Ondřej ; Pohl, Lukáš (referee) ; Blaha, Petr (advisor)
This thesis deals with the problem of control of permanent magnet synchronous motor. The introduction describes division of motors according to the structure and with the stress on the BLDC motor. Control methods are also discussed there including clarification of concepts related to the control itself. The advantages and disadvantages of individual methods are compared. Six-step commutation was chosen based on the simple implementation criterion. The work includes Simulink simulation, simulating the BLDC motor LINIX 45ZWN24-40 controlled by six-step commutation. The thesis contains a comparison of simulated motor speeds at various control parameters. The conclusion of the thesis deals with the possibilities for subsequent implementation.

Scooter with a BLDC drive
Doležal, Lukáš ; Kozovský, Matúš (referee) ; Veselý, Libor (advisor)
The bachelor thesis is focused on a design of a propulsion system for folding portable scooter. The BLDC motor is used as a propulsion. The thesis deals with the design of electronics for sensor control. Motor is controlled by six-step commutation method. In the practical part of thesis the controller of current is set and functionality is checked.

Low power BLDC electric drive
Štajner, David ; Červinka, Dalibor (referee) ; Pazdera, Ivo (advisor)
The aim of this diploma thesis is to introduce a construction and controlling of the EC motor. On a base of knowledge make up a EC motor model in Matlab Simulink, with a position scanning providing by Hall probe. The EC motor model should be with its behavior close to the real EC motor as much as possible. There were a given requirements on the motor. On the base of those requirements was chosen a real EC motor. Its catalog values were put in the EC motor model in Matlab and the results were compared with real data. Next task was to design a real controlling driver of EC motor, which should has a minimal size. This driver was constructed and thermal test was made a on given load.

1DOF helicopter model
Dědič, Roman ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis deals with the design of a 1DOF helicopter fixture and its mathematical model. An important part of this thesis is the identification of the parameters of the physical system and subsequent verification by simulation. Another part is the implementation of the BLDC motor control that was used on the physical fixture. The last part of the thesis deals with the design of the pitch attitude control of the 1DOF helicopter arm. PID controllers and sliding mode control are used here. All control methods were simulated and then verified on the fixture. Hardware operation was performed using an STM microprocessor and Simulink software.
