摘要
利用平面磁悬浮实现精密加工用工作台的定位子系统,建立的平面磁悬浮系统数学模型具有非线性和结构不确定性,提出区间矩阵最小上界方法设计鲁棒控制器。仿真结果表明,使用该控制器的平面磁悬浮闭环系统具有鲁棒性强、响应速度快,且能有效地提高加工精度。
The working table for precise machining had been realized through planar magnetic levitation system.The planar magnetic levitation system was a nonlinear uncertain system,the interval matrix minimum upper bound methods was proposed to design robust control.The simulation result showed that the controller which used the planar magnetic levitation closed-loop system had the strong robustness,the quick speed of response and machining precision can be effectively increased.
