【Abstract】 This paper analyses the influence of the track disturbance when the suspended electromagnetic is running on the track. And expatiates on the dual position feedback idea and point out that the idea can make the electromagnetic to resist the high frequency disturbance of the track. It also shows the way to design the signal filter and discusses the problem to be conquered in signal processing. At last it gives the simulating results. By comparing to the traditional PID control algorithm, it proves that the idea can solve the track disturbance problem very well.更多还原
