PMSM Drive Sensorless Control
Graf, Miroslav ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
Bachelor's thesis "PMSM Drive Sensorless Control" concerns about stage reconstructors by PMSM drive control. It describes Model Reference Adaptive System and Kalman filter. Both stage reconstructor are practically implemented at microprocessor and using the method "target in the loop" the functionality of both reconstructors is verified.

Electrical Drives Predictive Control Algorithms
Mynář, Zbyněk ; Vavřín, Petr (referee) ; Václavek, Pavel (advisor)
This work deals with the predictive control algorithms of the AC drives. The introductory section contains summary of current state of theory and further description and classification of most significant predictive algorithms. A separate chapter is dedicated to linear model predictive control (linear MPC). The main contribution of this work is the introduction of two new predictive control algorithm for PMSM motor, both of which are based on linear MPC. The first of these algorithms has been created with the aim of minimizing its computational demands, while the second algorithm introduces the ability of field weakening. Both new algorithms and linear MPC were simulated in MATLAB-Simulink.

Simulation models of electric drive vehicles
Bílý, Lukáš ; Huzlík, Rostislav (referee) ; Havlíková, Marie (advisor)
The work deals with creating a DC electric motor drive. The model is composed of electrical power from the engine model and transistor pulse converter load, which are joined together and completed the anchor and regulate the flow control engine speed. Great attention was paid to the determination of losses in the load drive electric vehicles and create a model of electric power load. The real work was verified by an experimental model of an electric vehicle Car4 the available parameters.

Mathematical model of synchronous motor width permanent magnet
Fajkus, Petr ; Klíma, Bohumil (referee) ; Huták, Petr (advisor)
The work is focused on the design of synchronous motor control with field weakening possibility. At present synchronous motors used in many applications. Often is used synchronous motor with permanent magnets. This type of motor may have different transverse and axial inductance. In most cases it is desirable to design the engine using a computer model. Therefore the synchronous motor described mathematically in order to create the model of motor. At work is also crated model of synchronous motor control. The control is designed for the highest possible speed range. Therefore, the motor control is consist of two parts. Speed is controlled by voltage in the first part. In the second part speed is controlled by field weakening. Everything is created and simulated in a computer program MATLAB-SIMULINK.

Chlup, Jaroslav ; Skalka, Miroslav (referee) ; Janda, Marcel (advisor)
This project deals with simulation´s possibilities of air flow in electric machines. A finite element method is the final element technique. Aim of this project is conversion universal formula for calculation friction dissipation factor. For its location is necessary to create 27 simulations according to the 2. plan order. Usage programme MATLAB for processing results obtain requisite algorithm for calculation friction dissipation factor.
