Abstract :
Although the railway switch sensor can measure the switch in real time, its measuring stability is still a problem. To reduce the dynamic measuring error in railway switch sensor, the switch sensor collecting circuit is analyzed, a predictive control method is introduced and an identified model of hall sensor in real time is built. At last, a new predictive compensating model is designed, which can improve the switch sensor dynamic performance. Thus this will make it easy to be applied in railway signalling.
