摘要
设计了一种主动磁悬浮轴承转子系统的解耦控制方法——基于特征模型的交叉反馈控制。使用特征模型控制算法替代PID算法,加入交叉反馈解耦项,将自适应功能的特征模型控制与解耦功能的交叉反馈控制相结合。建立转子系统的数学模型,用Simulink软件对控制系统进行仿真分析,证明控制算法可行。通过实验观察在不同衰减因子下转子高速旋转时的轴心摆振幅度,可确定最佳补偿量。
A decoupling control method for active magnetic bearing rotor system,characteristic model based cross-feedback control is designed.The characteristic model control algorithm is used to replace the PID algorithm,and the cross-feedback decoupling term is added,then,the feature model control with adaptive function is used with the cross-feedback control with decoupling function to esfablish,the mathematical model of the rotor system and then,simulate and analyze the control system by Simulink software.It is proved that the control algorithm is feasible.In the experiment,the amplitude of the axial swing of the rotor at high speed rotation under different attenuation factors is observed,which is used to determine the optimal compensation amount.
