为了在高速区有效操纵列车,无论列车长度如何都需要控制系统能够提供稳定的制动力。在设计制动控制系统过程中,由于粘着和制动材料的摩擦系数变化而导致的模型不确定性是一个需要首先考虑的问题。提出利用滑模控制原理设计一种全新防滑控制系统。相比于常规控制方式,仿真结果证明,在非线性制动动力学方面,基于滑模控制的防滑控制系统具有良好的性能。
In order to operate the train efficiently in the high speed zone, the control system is required to provide a stable braking force regardless of train length. Model uncertainty in the design of a brake control system due to changes in the coefficient of friction of the adhesive and brake materials is a problem that needs to be considered first. A new sliding control system based on sliding mode control is proposed. Compared with the conventional control methods, the simulation results show that the sliding mode control based anti-skid control system has good performance in nonlinear braking dynamics.
