摘要
为了提高永磁同步电机的动静态性能,根据永磁同步电机(PMSM)的数学模型和基本原理,在逆变器环节将电压空间矢量(SVPWM)代替传统的SPWM算法,该方法能够实现变频调速并且能够有效地提高直流侧电压利用率,降低定子三相电流谐波含有率,提高系统运行性能。最后利用MATLAB搭建了两种算法的仿真模型,仿真结果表明SVPWM控制系统比SPWM控制系统具有更好的动态稳定性以及实时跟踪技术。
tn order to improve the static and dynamic performance of permanent magnet synchronous motors,basing on permanent magnet synchronous motors (PMSM)mathematical model and basic principles,we use the voltage space vector(SVPWM)instead of the traditional SPWM algorithm in the inverter,we can achieve frequency modulation speed and improve the utilization rate of DC voltage effectively in this method,rerducing the stator phase current harmonic ratio, improving the system performance.Finally,building the simulation models of two algorithms by MATLAB,the simulation results show that the SVPWM control system than SPWM control system has better dynamic stability and real-time tracking technology.
