多目标约束的电动汽车转向控制方法

Special control method of electric vehicle with multi-objective constraints

以八输入二自由度汽车模型为基础,根据并行优化算法理论和Pareto占优理论,采用多目标约束控制算法对车辆进行建模并建立目标函数.分两层设计汽车控制器,第一层获得目标空间的Pareto最优前沿,第二层把第一层中选择的区间目标作为约束优化的一个最重要指标.在Matlab环境下进行了仿真试验,以验证控制器的准确性.

Based on the parallel optimization algorithm and Pareto dominance theories, a vehicle model is established and the objective function established by the eight input two degree of freedom vehicle mod- el. The algorithm is divided into two layers, the first layer of which is to obtain the target space of the Pa- reto optimal front, and the second layer of which is, as the most important index of constrained optimiza- tion, to carry out the simulation test in Matiab environment to achieve the accuracy of controller.
