Speed Adjustment Braking of Automatic Train Operation System Based on Fuzzy-PID Switching Control

Speed adjustment braking of Automatic Train Operation (ATO) system is studied in this paper. The characteristics of the train traction and the single phase of speed adjustment during the train braking are firstly described. Then, a mathematical model is introduced with the form of the experimental data. A Fuzzy-PID switching controller is first proposed on the ATO system, thus improving the response of the system and accuracy. Finally, the braking method is shown to be true and comfortable for the passengers through the smooth switch numerical example.
