摘　　要：磁悬浮开关磁阻电机(BSRM)在运行时由于转子的不平衡振动会使系统的稳定性和安全性受到严重影响,在介绍了BSRM转子悬浮力产生原理的基础上,推导出转子的动力学方程。给出BSRM悬浮力解耦控制模型,利用自抗扰控制器中TD滤波器优越的低通滤波特性,基于坐标变换的思想,设计了BSRM转子的不平衡振动补偿策略,对BSRM转子的不平衡振动进行实时动态补偿。仿真结果验证了该策略的有效性,设计的基于自抗扰控制器和坐标变换的方法成功实现了对BSRM转子不平衡振动的补偿,而且基本消除了转子的不平衡振动对BSRM系统的影响,控制系统性能优良。The bearingless switched reluctance motor(BSRM)while operating may affect its system stability and securityseriously due to the rotor unbalance vibration.The suspension force generation principle of the BSRM rotor is introduced to deduce the kinetic equation of the rotor.According to the suspension force decoupling control model of BSRM,superior lowpass filtering characteristic of the tracking differentiator(TD)in active disturbance rejection controller and the thought of coordinatetransformation,the unbalanced vibration compensation strategy of BSRM rotor is designed to perform the real-time dynamic compensation for the unbalance vibration of BSRM rotor.The simulation results verify that the strategy is effective.The methodbased on active disturbance rejection controller and coordinate transformation can compensate the unbalance vibration of theBSRM rotor successfully,and almost eliminate the influence of the rotor unbalance vibration on the BSRM system.The controlsystem has excellent performance.
