摘要
为实现永磁同步电机的高精度控制,设计了一种积分滑模控制器。针对负载扰动问题,设计了一种改进的龙伯格负载转矩观测器。通过将观测值反馈至滑模控制器中,实现了对转矩电流的补偿。仿真实验表明,该负载转矩观测器能有效跟踪实际负载变化,且滑模控制器在负载变化时能有效维持转速的稳定性。
In order to realize high precision control of permanent magnet synchronous motor,an integral sliding mode controller was designed.To solve the load disturbance problem,an improved Luenberger load torque observer was designed,and the torque current was compensated by the feedback of the observer to the sliding mode controller.Simulation results show that the load torque observer can effectively track the change of the actual load,and the sliding mode controller can effectively maintain the stability of the speed when the load changes.
