Feedback Control of Pneumatic Brake of Urban Railway Train under ATO Mode

This paper presents an analysis of the accuracy of urban railway train´s parking together with an elaboration of the system structure and principle of parking control in ATO mode. Through the construction of the model of pneumatic brake unit, the non-linear character of pneumatic brake unit is analyzed, and thereby the strategy of feedback control based on the train´s position signal is given. Further on-vehicle tests have substantiated the feasibility of this method; meanwhile, the superiority of parking accuracy after the adoption of this method is also illustrated.
