Abstract Adhesion control plays an important role in metro traction motor driving. To perform the maximum utilization of adhesion, a full state observer is built to obtain the motor load torque. Then the adhesion coefficient is calculated to find the adhesion peak zone. The difference between two wheels in one bogie can cause unbalanced torque for parallel-connected motors. Meanwhile, considering the optimized adhesion utilization control, the traction motor drive control strategy with magnetic field weaken compensation is introduced. Finally, simulation and experiments are taken, and the correctness and validity are verified by the simulation and the experiments.

Key words： Parallel-connected motor control optimized adhesion utilization unbalanced torque magnetic compensation metro traction
