摘要
在分析永磁同步电机(PMSM)的数学模型和磁场定向矢量控制的基础上,采用空间电压矢量脉宽调制(SVPWM)算法,在Matlab/Simulink环境下搭建了永磁同步电机控制系统的速度和电流双闭环仿真模型。并通过实例电机的仿真,给出了仿真波形,其仿真结果达到了预期效果,证明了该模型的有效性。
Based on analysis of the mathematical model of the permanent-magnet synchronous motor(PMSM) and the principle of field-orientated vector control, this paper presents the basic principle and realizing method of SVPWM, builds the simulation model of the whole system with Matlab/simulink. Two control loops are used, including inner cturrent-loop and the outer speed-loop. By simulating the specific motor, the waveforms are presented, which achieves the expected effect. And the reasonability and validity has been proved.
