摘要
交流异步电机调速系统有SPWM和SVPWM两种调制方式,利用MATLAB/Simulink建立了SPWM和SVPWM调制方式下的异步电机控制系统仿真模型。通过这两种方式下的仿真结果对比表明SVPWM调制方式下磁链轨迹已接近圆形,起动和运行性能良好,系统的稳定性和可靠性都得到了提高。
There are two kinds of modulation methods in AC asynchronous motor speed control system：SPWM and SVPWM. This paper uses MATLAB / Simulink to build a simulation model of the SPWM and SVPWM modulation of the asynchronous motor control system. Comparison with the simulation results of the two methods show that the flux trajectory with SVPWM control is close to a circle,and this control strategy has excellent starting and operating performance,the stability and reliability of the system have been improved.
