摘要
五相感应电机参数复杂且存在谐波,要获得准确的磁链观测器值须选取合适的观测器。基于五相感应电机矢量控制系统模型对三种转子磁链观测器进行比较研究,通过Matlab/Simulink将搭建的电压型、电流型和基于扩张状态观测器(ESO)型转子磁链观测器闭环到五相感应电机控制系统进行仿真,以分析不同模型的磁链观测器的观测效果。仿真结果表明基于五相感应电机模型的ESO型转子磁链观测器效果更优。
The parameters of five-phase induction motor are complex and there are harmonics.In order to obtain accurate flux observer value,it is necessary to select an appropriate observer.Based on the five-phase induction motor vector control system model,three types of rotor flux observers are compared and studied.Through Matlab/Simulink,the voltage-type,current-type and the rotor flux observer based on the extended state observer(ESO)type are loop-closed to the five-phase induction motor control system for simulation to analyze the observation effects of the flux observers of different models.The simulation results show that the effect of ESO rotor flux observer based on five-phase induction motor model is better.
