摘　　要： 该文提出一种考虑外扰动和饱和特性的开关磁阻直线电动机的自校正位置控制方法,利用自校正方法的参数自调整特点,克服因制造精度、饱和以及外扰动造成的模型不确定所带来的控制精度损失。该文中开关磁阻直线电动机采用单入单出的离散模型描述,利用回归最小二乘法估计参数,并应用极点配置自校正算法进行过程控制。仿真和试验结果证明该方法在参数估计、位置跟踪响应速度和在扰动下的鲁棒性等均有很好的效果。 This paper presents a self-tuning regulator（STR） with considering external load disturbance and saturation characteristics for position control of a linear switched reluctance motor（LSRM）. STR is applied to overcome the position precision loss owing to the factors of nonlinear characteristics of LSRM, manufacturing imperfection, saturation characteristics of drivers and external load disturbances. In this paper, the LSRM system is described by the single-input, single-output discrete model and the parameters of the model are estimated by the Recursive Least Square algorithm. Then a STR based on the pole placement algorithm with considering external load disturbance and saturation characteristics is applied to the LSRM for accurate position tracking. The simulation and experimental results demonstrate that this method is effective in parameters estimation, position tracking response, robustness to the disturbances.
