将传统PID理论和LQR理论相结合,提出了一种易于工程实现的交叉PID集中控制器,解决了磁悬浮轴承系统中集中控制器普遍存在的设计复杂、实时计算量大、过度依赖精确的数学模型等缺陷。针对实验室的磁悬浮轴承试验平台,采用Matlab仿真软件进行了交叉PID集中控制系统的仿真研究。仿真结果表明,交叉PID集中控制器具有较好的控制性能,可以实现电磁轴承转子的稳定悬浮。

On the Active Magnetic Bearing Centralized Controller

By taking both PID and LQR theory into account,the paper proposes the Cross-PID centralized controller,which is easy to be realized in engineering. The method avoides many problems such as large real-time calculation,the complexity of controller design,excessive dependence on the precision of mathematical model,which are prevalent in centralized controller of AMB system.We simulated the controller system by the Matlab on the base of AMB testing platform.The simulation results show that the control system has good performance and can achieve the stable levitation of the rotor in active magnetic bearing systems.
