运用模糊控制和滑模控制方法分别对半主动悬架系统和防抱死制动系统进行控制,建立了半主动悬架和防抱死制动系统的联合仿真模型,同时建立协调控制器对制动系统和悬架系统进行协调控制,仿真结果表明车辆性能参数得到了有效改善。试验结果表明,车辆制动减速度增加15%,距离和制动时间分别得到13.86%和11.38%的减小,车身俯仰角和质心垂直振动加速度分别有18.1%和16.2%的减小,试验验证了仿真模型的正确性和协调控制策略的有效性。
The semi-active suspension system and anti-lock braking system are respectively controlled by fuzzy control and sliding mode control. The co-simulation model of semi-active suspension and anti-lock braking system is established. At the same time, Dynamic control system and suspension system for coordinated control, the simulation results show that the vehicle performance parameters have been effectively improved. The test results show that the deceleration of the vehicle increases by 15%, the distance and the braking time decrease by 13.86% and 11.38% respectively, and the vertical pitch acceleration and the vertical acceleration of the vehicle body decrease by 18.1% and 16.2% respectively. The experimental verification The correctness of the simulation model and the effectiveness of the coordinated control strategy.
