摘　　要：为了实现对无轴承异步电机悬浮系统动态解耦控制,提出一种基于HJI理论无轴承异步电机悬浮系统滑模鲁棒控制方法。在悬浮系统建模时,将系统不确定性以及外界扰动考虑其中,并通过设计合适的滑模控制律满足HJI不等式鲁棒条件来确保控制系统的稳定性;最终,该方法实现无轴承异步电机悬浮系统动态解耦控制并提高了系统的稳定性和抗扰动性能。仿真和试验结果证明了该方法的有效性,能够实现两自由度无轴承异步电机径向悬浮力之间解耦控制。To realize the dynamic decoupling control of a bearingless induction motor suspension system,a sliding mode robust control method based on the HJI(Hamilton-Jaeobi-Issaes)theory for a bearingless induction motor suspension system was proposed.In modeling the suspension system,the system uncertainty and the external disturbance were considered,and the stability of the control system was ensured by satisfying the HJI inequality robust condition by designing an appropriate sliding mode control law.Finally,the method realizes the dynamic decoupling control of the bearingless induction motor suspension system and improves the stability and anti-disturbance performance of the system.Simulation and experimental results show the effectiveness of the method,which can realize the decoupling control of two degrees of freedom bearingless motor.
