摘　　要：将基于等效控制的变结构控制方法应用于汽车ABS,研究基于滑移率的控制算法。设计了由等效控制和切换控制组成的滑模变结构控制器,在此基础上进行了MATLAB/Simulink仿真验证,并给出干沥青路面、湿沥青路面以及雪路面的仿真结果。研究结果表明,基于等效控制的变结构控制方法,控制器设计简单,系统响应速度快,不论在高附着路面还是低附着路面,都能快速追踪目标滑移率,防止车轮抱死,控制效果理想,是一种有效的控制方法。The equivalent control of variable structure control method is applied to automotive anti - lock braking system, with this method to research control algorithm that based on slip ratio. On the base of Controller which is composed of equivalent control and switch control, simulation verification is done through MATLAB/ Simulink, dry asphalt pavement, wet asphalt pavement and snow road surface simulation results are given. The research results show that variable structure control method based on the equivalent control, its controller design is simple, and its system response speed is fast. Whether in high or low adhesion road, it can fast track targets slip ratio to prevent wheel to lock, and its control effect is ideal. So it is an effective control method.
