Multimodal Braking System Based on Deceleration Control

摘要

This paper proposes a “Multimodal Braking System based on Deceleration Control” with deceleration as braking control objective, including dynamic brake, permanent magnetic track brake and electro-pneumatic brake. Respectively, the validity of permanent magnetic track brake and deceleration control is analyzed in detail. The result shows permanent magnet track brake can achieve multilevel control by changing the angle of magnetic axis so that service braking can be realized, which can provide the deceleration of 0.56m/s2; compared with the traditional braking system, the steady-state error of braking system based on deceleration control is less than 0.062m/s2.
