Predictive relay space vector control of active frequency in systems in the AC electric drives

Abstract

Presented is a design conception of the automatic control system (ACS) based on the predictive relay space vector algorithm and applicable to the different types of semiconductor active frequency converters in the ac electrical drives. As an example, the ACS of the active voltage and active current rectifier, direct frequency converter and induction drive with the voltage source inverter are considered. The simulation and experimental results are presented.
