When the adhesion force coefficient between rail and driving wheel decreases, the electric motor coach has slip phenomena. We have already proposed the anti-slip re-adhesion control system based on disturbance observer. This system has the fine torque response for one driving wheel driven by one inverter-fed induction motor. However, the bogie of electric motor coach has four driving wheels driven two induction motors, which are, in some cases, driven by one inverter. In order to realize the anti-slip re-adhesion control system for the bogie of electric motor coach, this paper proposes a new anti-slip re-adhesion control based on disturbance observer and speed sensor-less vector control. The numerical simulation and experimental results point out that the proposed anti-slip re-adhesion control system has the desired driving wheel torque response for the tested bogie system of electric motor coach.
