【摘要】 为了解决永磁直线同步电机(PMLSM)运行过程中对系统参数摄动及负载扰动等不确定因素敏感的问题,结合内模控制和模型参考自适应控制各自的优点,设计了PMLSM自适应内模控制器(AIMC).仿真结果表明,自适应内模控制器同常规PI控制器相比,具有更好的动态稳定性和跟踪性能,对外界干扰具有较强的鲁棒性.更多还原

【Abstract】 The permanent magnet linear synchronous motor(PMLSM) position control system is sensitive to various disturbances such as the parameter perturbations,load disturbances and so on.An adaptive internal model controller(AIMC) is proposed to eliminate this trouble,integrating with internal model control and model reference adaptive control.Simulation results show that the adaptive internal model controller is superior to the conventional PI controller in dynamic stability performance and speed tracking power,and adaptive internal model controller has strong robustness to external disturbance.更多还原
