WHEEL SLIP AND RE-ADHESION CONTROL BY INDUCTION MOTOR VECTOR CONTROL FOR ELECTRIC MOTOR VEHICLES

초록

It is one of the most effective methods for improving the performance of electric railway vehicles to make better the wheel-rail adhesion characteristics. To study adhesion characteristic is to develop the equivalent reduction machine to experiment on the adhesion system. The experiment system makes it possible to change the wheel-rail adhesion force with various adhesion parameters, and therewith to test the adhesion control system with the reduction machine in a laboratory. In theory, in order to prove analysis for adhesion system and re-adhesion condition, simulation conducts for each condition. During test of adhesion control, to be sure detect, analysis for phenomenon conducts in skid state. The test equipment is composed of traction motor, torque-meter, clutch, and inertia body of cylinder type."
