永磁同步电机直接功率控制基本原理
Basic Theory of Direct Power Control for PMSM
摘要
Abstract
Based on the analysis of relationship of the active power, reactive power, torque and stator flux-linkage, a new direct power control(DPC) method for permanent magnet synchronous machine is presented in this paper. It selects optimum voltage vector to control the instantaneous power through optimum switching table which based on the sector of flux linkage and the output of the active and reactive power hysteresis. The goal of the method is to control reactive power as zero and improve power factor at the same output of active power. Both the results of simulation and experiment show the good performance and accuracy of the proposed method. Especially, this method has good application prospect in energy saving motor driven systems.关键词
