摘要

线性感应电机(LIM)具有成本效益，但由于非线性摩擦的存在，其定位精度较低。本文研究了利用高阶扰动观测器对直线滚珠导轨的非线性滚动摩擦进行建模和补偿的直线滚珠导轨精确定位控制方法。通过各种实验证明，该方法的定位精度小于±0.15 (μ m)。

A Proposal for Precison Positioning Control of Linear Induction Motor Using Nonlinear Friction Compensation and High-Order Disturbance Observer

The linear induction motor (LIM) is cost-effective, but exhibits low positioning precision because of the presence of nonlinear friction. This paper deals with the precise positioning control method of a LIM using a high-order disturbance observer and modeling and compensation for nonlinear rolling friction of a linear ball guide attached to the LIM. Through various experiments, we demonstrate that the positioning precision of our proposed method is smaller than ± 0.15 (μ m).
