摘　　要：针对一种适合于电动公交大客车上使用的新型直流牵引电机,研制了电动公交大客车的驱动控制系统,从理论上建立了新型电机在控制系统下的感应电动势、电磁转矩和转速的数学模型,并用试验数据验证了该数学模型的正确性。由于这种新型的电机具有大的起动转矩,所以可以提供较大的加速度;建立了新型电机的加速度控制系统,并使用根轨迹法来分析这种新型电机加速度的微分负反馈控制系统;仿真结果表明,这种新型电机的驱动控制系统具有非常好的响应特性和调节特性;装车实验结果表明, 该驱动控制系统的抗干扰能力强、调节特性快速、平稳,能很好地满足电动公交大客车的动力特性要求。The drive control system of the permanent magnetic direct current (PMDC) motor with the enhanced magnetism windings used in the electric transit bus is developed. The mathematics model of inductive electromotive force, electromagnetism torque and speed applied by control system is established from the theories and proved its correctness by the experimental data. Because of its big starting torque, the newly drive motor can supply a greater acceleration. The acceleration control system is set up and Root Locus Design is applied to analyze and design the acceleration differential feedback control system. The result of simulation show that the newly drive motor control system has extraordi-nary response characteristic and adjustable performance. Experiments of vehicle running show that the drive control systems antijamming ability is strong and the adjustable performance is fast and smooth, it can meet the demand of power characteristic very well.
