摘　　要：深入分析基于矢量控制的永磁同步电动机(PMSM)位置伺服系统电流滞环控制方案。为了实现高性能的位置伺服电流环控制,对比了常规电流滞环控制和三角波载波比较方式的电流滞环控制。在Mat-lab中搭建了两种电流滞环控制方式的仿真模型,通过仿真分析得出采用常规电流滞环控制对系统的整体性能影响比较大,而采用的三角载波比较方式的电流滞环控制容易获得良好的控制效果。采用的三角载波比较方式的电流滞环控制的仿真结果被进一步验证,并且为位置伺服系统的整体设计提供了理论基础。Hysteresis-band current-control scheme of PMSM position servo system based on vector control is analyzed deeply. For the sake of high-performance current-loop in position servo system, we studied general hysteresis-band current-control and triangular carrier wave hysteresis-band current-control. Simulation models of the two mode are build in Matlab, by the simulation analysis, we can know that general hysteresis-band current-control will seriously influence on performance of system, and triangular carrier wave hysteresis-band current-control can be used for good control performance. When triangular carrier wave hysteresis-band current- control is used, analytical results are good agreement with the simulation results, and the results can provide theoretical basis for the design of servo system.
