| 摘 要： | 针对主动磁轴承飞轮转子系统存在较多不确定因素的问题,设计了滑模变结构控制器,其中采用Lyapunov方法建立滑模面,由比例型到达律确定到达控制器,同时由Lyapunov第二方法证明了闭环系统的渐进稳定性.仿真结果表明,系统的位移和速度能在较短时间内收敛到零,抖振较小,系统动态响应较快,稳定精度较高,对外界干扰和参数变化具有较强的鲁棒性,从而达到了较好的控制效果.

| Abstract: | Aiming at the uncertainty in the flywheel rotor system based on active magnetic bearing,sliding mode variable structure controller is designed,which establishes sliding mode surface by Lyapunov method and determines arrival controller by approach law.Meanwhile,the asymptotical stability of the closed-loop system is guaranteed using Lyapunov second method.The simulation results show that the displacement and velocity of the system can be convergent to zero in short time and chattering is little,which can ach... |
