在电动客车中，当钢轨与驱动轮之间的粘着力系数突然减小时，电动客车会出现打滑现象。我们已经提出了基于普通干扰观测器的防滑控制系统。为了在附着力系数变化较大的情况下实现更稳定的防滑再附着控制，提出了一种基于一阶扰动观测器和新的转矩函数的防滑再附着控制方法。本文的数值仿真结果表明，所提出的防滑重粘控制能够很好地稳定调节电动客车的驱动轮扭矩。
In electric motor coaches, when the adhesion force coefficient between rail and driving wheel decreases suddenly, the electric motor coach has slip phenomena. We have already proposed the anti-slip control system based on ordinary disturbance observer. In order to realize the more stable anti-slip readhesion control in case of large variation of adhesion force coefficient, this paper proposes a new anti-slip readhesion control based on first order disturbance observer and new torque function. In the numerical simulation results in this paper, the proposed anti-slip readhesion control well regulates the driving wheel torque of electric motor coach stably.
