摘　　要：永磁直线同步电机(PMLSM)采用直接驱动方式,其动子上存在包括负载力、摩擦力和磁阻力在内的多重扰动力,这些直接作用在动子上的扰动严重地影响到直线电机的速度稳定性。提出了一种PMLSM抗扰动速度控制策略,基于扩张状态观测器(ESO)观测出多重扰动力对PMLSM的速度动态过程的扰动作用,引入跟踪微分器(TD)和非线性状态误差反馈(NLSEF)对这个扰动作用进行补偿,进而实现PMLSM一阶速度抗扰动控制。For PMLSM direct driven mode, multiple disturbed forces, including load force, friction and magnetic resistance, are acted directly on the rotor of PMLSM without any cushioning, so that they affect the speed stability of PMLSM. This paper presented a PMLSM speed control strategy with disturbance rejection, that was based on the expansion state observer used to observe multiple dis- turbed forces in dynamic process of PMLSM speed, a tracking differentiator（TD） and nonlinear state error feedbaek（NLSEF）. The disturbance can be compensated, thus the first--order speed control with disturbance rejection of PMLSM can be achieved.
