【摘要】 为了增强永磁直线同步电机(PMLSM)直接驱动系统的鲁棒性,改善系统受突加扰动情况下的性能,结合递归神经网络与模糊控制的优点,设计了基于递归模糊神经网络补偿器的PMLSM位置控制器。仿真结果表明,所设计的系统能实现对位置阶跃指令的快速无超调跟踪和稳态无静差,具有很强的鲁棒性,能够满足高精度、微进给永磁直线同步电机伺服驱动系统的要求。更多还原

【Abstract】 In order to enhance the robustness of permanent magnet linear synchronous motor(PMLSM) direct drive system,and improve its performance under suddenly disturbance,the recurrent fuzzy neural network compensator is desiged combining the merits of recurrent neural network and fuzzy control.Simulating results show that the designed method has strong robustness and strong tracking rapidity without overshot and zero steady-state error,and can satisfy requirments of the high precision and micro-feeding PMLSM drive system.更多还原
