Abstract
The drive control system of permanent magnetic direct current motor with enhanced magnetism windings used in the electric transit bus is developed. The mathematics model of the drive control system for this motor is established. The mode that the added-exiting magnetism field could be weakened and the speed of the motor could be controlled automatically is proposed and realized. The method of root locus design is applied to analyze the acceleration control characteristic. The results of simulation show that the drive motor control system has extraordinary response characteristic and adjustable performance. Experiments of vehicle running show that the drive control system's antijamming ability is strong, the adjustable performance is fast and smooth, and it can meet the demand of power characteristic very well.
