摘　　要：针对无铁心永磁直线同步电机(ILPMSM)存在d-q轴耦合效应、易受参数不确定性的影响,为实现系统的高性能控制,提出了一个带有延迟补偿的鲁棒控制器。该控制器由一个一阶参考模型的逆模型和一个积分项组成,不需要结合其他控制算法且不要求系统参数精确。采用系统传输延迟的逆模型来补偿系统时延的影响。与常规PI控制器相比,鲁棒控制器能很好地抑制ILPMSM系统的不确定性干扰,并对系统的传输延迟进行可靠补偿。仿真结果表明该方案有效地减少系统响应的超调,使系统具有良好的动态性能。For the characteristics of ironless linear permanent magnet synchronous motor （ILPMSM） system being influenced by disturbance due to d-q axis coupling effect and parameters varieties, the investigated robust controller with system delay compensation is desired to achieve high performance. The proposed controller consists of an inverse of the first-order reference model and integral term. The proposed algorithm does not need to be combined with other control algorithms and the system parameters are not required to be known precisely. The system delay compensation adopts an inverse system delay model to compensate the system transport delay effect. Compared with PI controller, robust controller can restrain the effects of uncertainty disturbances and compensate for system transport delay in the ILPMSM system. Simulation result confirms the control scheme can reduce the overstrike of system with good dynamic response and dynamic characteristics.
