| 摘 要： | 深入分析了SPWM电流滞环控制的永磁同步电动机伺服系统及其速度环的变结构控制方案。电流环是PMSM伺服系统中的一个重要环节，采用SPWM电流滞环控制可方便地提高伺服系统的控制精度和响应速度，改善系统的控制性能。速度环变结构控制方案使伺服系统较常规的PI控制方案有更好的快速性和鲁棒性。从仿真结果可知，采用SPWM电流滞环控制及速度环的变结构控制能够改善系统的响应速度，基本实现无超调，且对负载扰动和参数变化的鲁棒性也有所改善。

| Abstract: | SPWM Hysteresis-band current and variable structure control scheme of PMSM servo system were analyzed deeply. Current-loop is an important part of PMSM servo system, by the simulation analysis, SPWM hysteresls-band currentcontrol can be used for good control performance and advanced control precision and response. Variable structure control of speed-loop was used in servo system, which better fastness and fine robustness will be achieved. When SPWM Hysteresisband current and variable structure control scheme were used, the simulation results demonstrate that the system has the ad- vantages of rapid response and no ever-shoot and has stronger robustness to change of system parameters and the disturbance of load. |
