摘　　要：对电动汽车再生制动过程中的防抱死控制方法进行研究,提出了通过调节驱动电机的电制动力来防止车轮抱死,即电气ABS。根据轮胎魔术公式和直流电机数学模型建立了1/4车辆动力学模型;使用二阶线性自抗扰控制器设计以最优滑移率为控制目标的电气ABS控制系统;采用免疫遗传算法获得线性自抗扰控制器的最佳参数。仿真结果表明:基于线性自抗扰控制的电气ABS对内部和外部扰动有很强的鲁棒性,具有良好的制动性能。The Anti-lock braking process of regeneration control method was studied. A novel method was proposed that motor regenerative braking and reversal braking torque were controlled to prevent wheels from locking,that is electric ABS. A dynamics model for the quarter electric bus is established based on tire Magic Formula and the model of motor. ABS controller was developed based on LADRC with the aim at anticipant slippage. In order to get optimum parameter of LADRC,immune genetic algorithm is introduced. The stimulation show that the controller based on LADRC is robust to the system internal and external disturbances. And have good braking performance.
