提出了一种新的逆变器供电感应电机驱动的电动通勤列车防滑/防滑重粘控制系统。设计了一种基于干扰观测器的驱动轮轨瞬时切向力估计器。所提出的系统的扭矩命令调节超过该估计的切向力，以避免驱动轮出现不希望的打滑现象。针对实际的电动通勤列车转向架，我们已经提出了基于普通干扰观测器和无速度传感器矢量控制的防滑/防滑重粘控制系统。该系统具有良好的转差率转矩响应。但该系统没有考虑实际电动通勤列车转向架动力学的振动现象。为了将抗滑/防滑重粘控制推广到考虑振动现象的实际转向架系统中，提出了一种基于一阶共振频率的高阶扰动观测器的抗滑/防滑重粘控制方法。数值仿真结果证实了所提出的控制系统的有效性。
This paper proposes a new anti-slip/skid re-adhesion control system for electric commuter train driven by inverter-fed induction motors. This paper designs an instantaneous tangential force estimator between driving wheel and rail, which is based on disturbance observer. The torque command of proposed system regulates to exceed this estimated tangential force in order to avoid undesirable slip phenomenon of driving wheels. For the actual bogie of electric commuter train, we have already proposed the anti-slip/skid re-adhesion control system based on the ordinary disturbance observer and the speed sensor-less vector control. This system has the fine torque response for slip condition. However, this system does not consider the vibration phenomenon of actual bogie dynamics of electric commuter train. In order to extend the anti-slip/skid re-adhesion control to the actual bogie system considering the vibration phenomenon, this paper proposes a new anti-slip/skid re-adhesion control based on a new high order disturbance observer considering the first resonant frequency. The numerical simulation results confirm the validity of the proposed control system.
