主动式磁浮主轴系统的最优控制

Optimal Control in Spindle System with Active Magnetic Bearing

应用最优控制理论，对磨床的磁浮主轴系统的稳态不平衡响应实施最优控制，建立了系统的有限元模型；采用阻尼衰减控制，提高了转子的抗失稳、抗干扰能力，使转子的整体响应水平明显改善。仿真计算表明，控制效果符合要求。

Optimal control on the steady imbalance response of the electromagnetic suspension ina high-speed grinding spindle system is carried out on the basis of optimal control theory.A finiteelement model of the system is established.By using the damping attenuation control.method,the ability of the system to reject disturbance and instability is improved.The control effect isproved to meet the requirement through simulation and calculation.
