摘要: 为解决电动汽车电机制动时出现抱死的问题,对全桥调制与半桥调制下永磁无刷直流电机制动转矩进行比较,发现全桥调制下电机制动能量回收具有明显优势;分析了全桥调制下电机制动实现防抱死控制基本原理,利用PID控制设计了基于滑移率控制的电动汽车电机制动ABS控制系统。根据全桥调制下电机制动电气模型,在车辆单轮制动动力学模型基础上,建立了基于Matlab/Simulink的电动汽车电机制动模型。在高、中、低3种附着系数路况以及对接情况下进行仿真,仿真结果表明:系统反应迅速,控制精确;通过PID控制器控制,滑移率保持在理想值,系统稳定性强,能够较好地实现ABS功能。

Abstract: By comparing the braking torque of permanent magnet brushless DC motor in full and half bridge modulations,the advantages of motor braking energy recovery in full-bridge modulation are obvious.Then the Anti-lock Braking System(ABS) with pure electric braking based on slip-rate in electric vehicle is designed with PID strategy by analyzing the control principle of ABS based on electric braking in full-bridge modulation,so that the problem of wheel lock during braking is solved.A single wheel vehicle dynamics model is developed in Matlab/Simulink based on the braking mathematical model of brushless direct current motor in full-bridge modulation,the model is simulated on the high,middle and low-adhesion road.The results show that the created system has fast response,precise control and good stability,the slip rate is kept within ideal range,the ABS runned effectively.

Key words: electric vehicle, motor regenerative braking, Anti-lock Braking System(ABS), PID control
