EMS型磁浮列车模块的基于逆系统的解耦控制

Inverse System-Based Decoupling Control of EMS Type low-middle speed Maglev Train Module

针对EMS型中低速磁浮列车的模块内部两个悬浮端点之间的耦合问题,本文采用基于逆系统的解耦方法,把悬浮模块系统解耦为两个独立的单输入单输出线性系统,并用线性系统理论的状态反馈方法为这两个线性系统配置极点,使它们按照预期的性能指标稳定。最后对整个控制系统进行了仿真研究和实验研究。仿真和实验结果表明,本文设计的解耦控制器能很好的抑制模块内部的耦合,能提高模块的悬浮控制性能。

A decoupling control approach based on inverse system theory is developed to reject the state coupling of the module of EMS type low- middle speed maglev train. Firstly, the module system is reduced to two linear subsystems when compensated by its inverse system. Then linear controllers are designed according to the system’s requirement. Finally, simulations and experiments are carried out. The simulating and experimental results show that the decoupling controller can reject the state coupling of the modul...
