| Abstract |
This paper proposes an effective way to realize fast readhesion control of single-inverter-multiple
motor traction drives. To do this, multirate sampling observers are introduced to all axles in order to
estimate precise speed and load torque at every sampling instant. The slip-slide is detected by using
the amount of the load torque correction estimated from the multirate sampling observer, which is
insensitive to the effect of slope. The performance of the proposed control scheme is verified by
comparing with the conventional method. |
