摘　　要：基于遗传算法和改进粒子群优化算法相结合的智能优化方法对车辆滑模控制器进行优化,并在其基础上应用到半车悬架模型中.首先利用模糊控制的控制方法设计车身姿态补偿模糊控制器,然后结合两种控制策略,确定最终的半主动悬架控制策略,抑制车身俯仰角.实验结果表明,该控制器性能优越,能有效抑制汽车行驶过程中车身俯仰角的变化,改善汽车行驶的平顺性.Based on the intelligent optimization method combining genetic algorithm and improved particle swarm optimization algorithm,we optimized the vehicle sliding mode controller,and on the basis of which it was applied to the semi-vehicle suspension model.Firstly,the body attitude compensation fuzzy controller was designed by using the fuzzy control method.Secondly,the final semi-active suspension control strategy was determined by combining the two control strategies to suppress the body pitch angle.The experimental results show that the controller has excellent performance,which can effectively suppress the variation of the body pitch angle during the process of driving and improve the smoothness of the vehicle travel.
