摘要
利用经典的PID控制器针对1/4悬架进行主动悬架的设计。考虑到悬架多个性能指标的协调,本文利用遗传算法进行多个目标的优化及参数整定。经过优化,悬架的各个性能指标都有非常明显的降低,舒适性、安全性以及操纵稳定性都得到了非常明显的改善。
It utilizes classical PID control to design an active suspension controller for quarter car model.Considering the tradeoff between the suspension performance indexes,this paper utilizes genetic algorithm (GA) to carry out muti-objective optimization and parameter tuning. After optimization, all the suspension performance indexes are decreased obviously, and comfort, safety, handling improved significantly.
