Aiming at the five degree of freedom(Five-DOF) AMB system,MIMO integral sliding mode variable structure control(ISMC) algorithm is designed based on its equation of state with the output decoupling.The performance of AMB based on conventional PID control and ISMC are compared by MATLAB/Simulink.The results show that the Five -DOF AMB system with the MIMO integral sliding mode controller has better dynamic and strong robustness.%针对5自由度主动磁悬浮轴承系统,根据其输出解耦的状态方程,设计了一种多输入多输出积分滑模变结构控制算法.利用MATLAB/Simulink分别对常规PID控制和积分滑模变结构控制进行仿真和比较,结果表明,5自由度主动磁悬浮轴承系统的多输入多输出积分滑模变结构控制方法具有良好的动态性能和鲁棒性.
