Time-domain design of motor drive current regulators using genetic algorithms

In this paper, the design of switching modulators that provide gating signals to the semiconductor devices in a power electronics converter is addressed. Specifically, modulators for permanent magnet synchronous machine drives are considered. Both current source-based and voltage source-based modulators may be used in a current-regulated drive application. The choice of the class of modulator, the specific type of modulator, and the parameters of the modulator and control constitute a significant design problem. Performance metrics to assess the quality of a design are set forth. They are used in conjunction with a genetic algorithm to automatically select the class, type, and parameters of the modulator
