Abstract :
The authors developed a re-adhesion control algorithm for a traction inverter system with vector control for commuter train applications. The re-adhesion algorithm consists of creep control, estimated traction force control, oscillation suppression control and all wheel slip suppression control. As the result of the running tests with new control, the adhesion performance was improved by more than 20% and passenger comfort was greatly improved, regardless of the conditions of the rail, gradient and kind of rolling stock
