摘要
对双轮驱动电动汽车的加速过程进行力学分析建立了四分之一车辆动力学模型,以车轮滑转率为控制对象,提出一种基于滑模变结构控制的驱动防滑控制系统。设计了双轮驱动电动汽车驱动防滑系统的滑模变结构控制器,采用饱和函数可以很好地削弱系统响应的抖振现象。通过Matlab/Simulink软件对所设计系统进行仿真,仿真结构表明滑模变结构控制器能够很好地跟踪路面最佳滑转率的变化,驱动力矩的变化平稳。
In this paper, a quarter vehicle dynamics model is established through analysis to two-wheel drive electric vehicle, and an acceleration slip regulation （ASR） algorithm based on sliding mode variable structure control is realized. The sliding mode controller is designed and the saturation is used to reduce chattering in the system response. The software of Matlab/Simulink is used to validate the design. The results show us that the system can work well to follow variety of optimal slip ratio on different roads and the driving torque can change smoothly.
