【摘要】 滑模控制作为变结构控制的一大分支，因对被控对象精确数学模型依赖性低，而具备较强的鲁棒性。本文将滑模控制算法应用到永磁同步电机伺服控制系统的位置环中，详细介绍了其状态变量的设置、滑模面以及趋近律的选取并推导了控制器输出量的表达式。仿真和实验结果证明，采用滑模位置控制器的永磁同步电机伺服系统可以较好地跟随位置给定信号，且抖振问题也得到了有效的解决。更多还原

【Abstract】 As a major branch of variable structure control, sliding mode control has strong robustness due to its low dependence on the precise mathematical model of the controlled object. In this paper, the sliding mode control algorithm was applied to the position loop of permanent magnet synchronous motor servo control system, and the setting of its state variables, the selection of the sliding mode surface and the reaching law were introduced in detail, and the expression of the controller output was deduced. Simulation and experimental results show that the permanent magnet synchronous motor servo system with the sliding mode position controller can follow the given position signal well, and the chattering problem has also been effectively solved.更多还原
