在矢量变换的基础上,提出并实现了基于数字信号处理器(DSP)的永磁同步电动机(PMSM)的位置控制系统,利用永磁同步电动机自带的旋转变压器来进行矢量控制与位置控制,大大简化了系统的硬件,给出了电流环、速度环与位置环的算法流程,在开发的基于DSP的电机控制平台上进行了试验验证,并利用PC104完成上位机的监控,试验结果表明,该位置控制系统具有良好的性能。

A digital signal processor(DSP)based position control system for permanent magnet synchronous motor(PMSM)is presented and developed on the basis of vector transformation.Vector control and position control are implemented using the inherent revolving transformer of PMSM,which greatly simplifies the hardware of the system.The algorithm procedures of current loop,speed loop and position loop are offered.An experiment is carried out on the DSP-based PMSM control platform for empirical validation.System surveillance is accomplished by using the PC104 computer.The experimental results show that the position control system exhibits favorable performance.
