摘　　要：在永磁电动机伺服系统优化控制中,直线永磁同步电动机是高精伺服系统的驱动设备。由于系统结构结构的非线性和系统阻力扰动的不确定性会导致伺服系统输出存在明显的抖振现象。为了优化调速控制精度,对于速度跟踪问题,提出以模型参考自适应结构为基础,采用滑模控制方法使速度跟踪误差沿滑模线快速衰减到零;针对系统输出的抖振现象,进一步设计阻力扰动估计器对系统阻力扰动进行估计和补偿。仿真结果表明所提方案能有效保证直线伺服系统的控制精度,并使得系统对参数变化和外部扰动具有较强的鲁棒性。To achieve high precision speed control, the sliding mode control was introduced in the reference mode adaptive control to ensure that the mode following error is driven rapidly to zero on the sliding mode line. Then a resistance perturbation estimator was designed to estimate and compensate the resistance perturbation and to minimize the chattering of the sliding mode control. Simulation results show that a high servo precision controller of the linear servo motor obtained based on the proposed strategy can make the system have strong robust against parameter variations and external disturbances.
