摘要: |
对于磁悬浮列车的悬浮控制,如果取悬浮间隙、电磁铁速度以及电流为状态变量进行反馈控制,在实验中控制参数的稳定区间较小,不易寻找控制参数的稳定区间,而且控制参数之间的影响比较严重;采用悬浮间隙、电磁铁速度以及磁通密度作为状态变量进行反馈控制的方法可以解决上述问题,便于实际的调试工作。仿真结果证明了第二种方法的有效性。 |

Abstract: |
It is not easy to find a set of control parameters to stabilize the magnetic suspension system when the suspension clearance, velocity of electromagnet and current are taken as the feedback state variables, and control parameters affect each other. To tackle those problems, the suspension clearance, velocity of electromagnet and magnetic flux are taken as the state variables. It is easy to find the stable control parameters in experiment when this method is taken. Simulation proves the validity of the second control method. |
Keywords: magnetic suspension system magnetic flux feedback current-loop |
