摘要
永磁同步电动机(PMSM)是当今变速交流传动非常受欢迎的感应电动机,将矢量控制策略应用到PMSM的调速系统中,可以得到与直流电动机调速系统相媲美的性能。在MATLAB/SIMULINK仿真环境中,选用矢量控制中的id=0与最大转矩电流比(MTPA)进行PMSM调速系统的建模与分析,从转矩、转速、三相电流波形对两种控制策略进行了比较,得出两种控制策略都可应用于不同场合,对工程实践有一定的指导和借鉴意义。
Permanent magnet synchronous motor(PMSM)is a popular induction motor for variable speed AC drive.The vector control strategy can be applied to the speed regulation system of PMSM,and the performance comparable to that of DC motor speed control system can be obtained.In the MATLAB/SIMULINK simulation environment,the i d=0 and the maximum torque per ampere(MTPA)in vector control are selected.The modeling and analysis of the PMSM speed control system are carried out.The two control strategies are compared from the torque,speed and three-phase current waveform,and the two control strategies can be used in different situations and have some guidance and reference significance to the engineering practice.
