Design of High Performance Converter for PMSM Applied to Flywheel Energy Storage Array

Abstract

A multi-objective visual design method of permanent magnet synchronous motor (PMSM) drive system which is applied to flywheel energy storage array is proposed. D-partition technique is applied to obtain the parameters stable region. Besides, frequency-domain specifications such as gain margin and phase margin, time-domain specifications such as overshoot and settling time are considered. Furthermore, a parameters design method is proposed and the optimized performance can be derived which meets the time- and frequency-domain specifications simultaneously. Simulation and experimental results verify the effectiveness and practicability.
