Electrical machines have now become part of our lives, it is impossible to imagine our every day without them. This is due to the incredible development of electronics in recent decades.
In my thesis I examine the control of a permanent magnet cylindrical rotor sinusoidal field synchronous motor and a short-circuit rotor induction motor with simulations. The simulations were performed in Matlab Simulink.
In the first chapter, there is an introduction to why electrical machines are so important in today's life.
In the second chapter I present the structure of a general regulated electric drive. I review the main components of the electric drive and present the operation of the model.
In the third chapter I examine the various current vector controls of a permanent magnetic synchronous machine. The tested regulations include three phase pulse width modulation control (PI controllers in a, b, c coordinate system), space vector ISZM controller control (PI controllers in d, q coordinate system), hysteresis control.
In the fourth chapter, I examine the various current control of a short circuit rotor induction machine. The tested regulations include three-phase pulse width modulator control (PI controllers in d, q coordinate system), space vector ISZM controller control (PI controllers in a, b, c coordinate system), hysteresis control.
In the fifth chapter I show what is the task of a general grid converter and what parts it can be build.
In the sixth chapter, I examine how the grid converter and the machine side converter work together with a common DC circuit. The supplied electric machine is an short-circuit rotor induction motor. Both converter have hysteresis current vector control.
