Plenary lecture „Development of control methods in power electronics and drives” will be given by professor Marian Piotr Kaźmierkowski
The lecture reviews the technology status of control strategies for PWM rectifier/inverter-fed induction motor drives developed in the last 40 years. Since not all of them have found wide industrial applications, only the most popular strategies commercially used and some of the future trends will be discussed. After introduction and classification the torque control methods will be presented in two main groups: linear (FOC, DTC-SVM) and nonlinear (DTC, DSC) controllers. Also, the group of modern nonlinear control methods (FLC, Multiscalar) will be overviewed. Among future trends a special emphasis will be given on the Model Predictive Control (MPC). This trend is supported by the DSP producers that increase the operation speed and computation capacity as well as offers specialized circuits (FPGA). Therefore, it is possible to implement an on-line optimization using MPC principles. In the second part the main control techniques for PWM rectifiers will be reviewed with emphasis on the similarities to motor control schemes. Specific problems of the grid connected operation in the generator mode (in renewable energy systems) will be highlighted. Selected oscillograms accompany the presentation in order to illustrate properties of the described control strategies.
