Re-adhesion control of electric motor coach based on disturbance observer and sensor-less vector control

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 a disturbance observer. This system has the fine torque response for one driving wheel driven by one inverter-fed induction motor. However, the bogie of an electric motor coach has four driving wheels driven by two induction motors, which are driven by one inverter. In order to realize the anti-slip re-adhesion control system for the bogie of an electric motor coach, this paper proposes a new anti-slip re-adhesion control based on a disturbance observer and speed sensor-less vector control.
