PMLSM控制系统的仿真研究

Research on Simulation of Control System of PMLSM

根据永磁直线同步电机数学模型理论,利用Matlab/Simulink软件搭建PMLSM的模型,并进行了基于传感器矢量控制的仿真和基于MRAS无位置传感器矢量控制的仿真。仿真结果表明,基于MRAS无位置传感器矢量控制系统解决了由传感器带来的问题,但其估计精度和动态性能相对基于传感器矢量控制的仿真有所下降。

This paper created the model of PMLSM through using Matlab/Simulink based on math model of PMLSM, and simulated two vector control systems based on sensor and MRAS position-sensorless. After Comparing the simulation results, the vector control system based on MRAS position-sensorless could solve the problem brought by sensor, but its estimation precision and dynamic performance were inferior to the one based on sensor.
