| 摘 要： | 针对永磁同步电机位置控制系统,设计分数阶滑模变结构控制器,以代替传统PID三闭环串级控制结构的转速环和位置环控制器。针对电机运行时负载转矩会受到外界干扰的问题,设计负载转矩观测器。仿真结果表明分数阶滑模控制器有良好的动态和稳态性能以及良好的鲁棒性。

| Abstract: | A fractional-order sliding mode controller is designed for the position control system of PMSM.The controller for the velocity loop and position loop of tradition PID triple closed loop cascade structure is replaced by the fractional-order sliding mode controller.Moreover,a load torque observer is designed for external load disturbances which the motor encounters with in running.Simulation results show that this fractional-order sliding mode controller is not only of good dynamic and steady state performance but also perfect robustness. |
