摘　　要：提出一种基于上位机的永磁同步电机(PMSM)电流环和速度环控制方法,在PMSM矢量控制的基础上,通过电流环零-极点对消原则和速度环期望中频区宽度,给出了电流环和速度环控制器参数设计方法。此外,对PMSM给定零角度电流矢量,实现了电机零位角的自动鉴别。最后,在开发的基于DSP的PMSM控制系统及上位机软件平台上实现了上位机的电流环和速度环控制参数自动计算及实验数据的记录、上传及曲线显示,速度阶跃响应速度快,超调量小。实验结果证明了该方法的有效性及工程实用性。A permanent magnet synchronous motor （PMSM） current loop and speed loop design method is presented based on host computer.On the basis of vector control,current loop and speed loop control parameters design methods are given through the principle of zero-pole cancellation and the speed loop expected width of mid-frequency interval respectively.Furthermore,by giving zero-angle current vector on PMSM,motor zero angle auto identification is realized.Lastly,PMSM control system based on DSP and host computer software platform is developed.Host computer autocalculating of current loop and speed loop control parameters is carried out and experimental data recording,upoading and curve displaying are executed.The speed step has fast response and lower overshoot.The experimental results show the effectiveness and engineering practicability of the method.
