机床磁悬浮主轴的变结构控制——Backstepping方法

本文基于机床磁悬浮主轴的非线性模型，采用反演设计的方法，提出了一种非线性的控制策略，电磁机械系统的反演变结构控制。在对主轴转子位置、速度及电流进行测量的基础上，控制器解决了主动磁主轴控制中存在的非匹配不确定性问题，实现了鲁棒镇定，仿真实例证明了控制器的有效性

Variable structure control of magnetic floating spindle for machine tools

Based on nonlinear model of magnetic floating spindle for machine tools and using the method of inversion desingn, this paper puts forward a nonlinear control strategy, i. e. inversion variable structure control of electromagnetic- mechanical system. On the basis of measuring the position, speed, speed and electric current of spindle rotor, the controller solves the problem of uncertainty of non - matching in active magnetic spindle control and implements robustness and stability. Simulation examples prove that the controller is effective.
