| 摘 要： | 车辆半主动悬架能够显著改善车辆行驶的平顺性和稳定性.控制算法需根据路面及车速的变化动态优化振动加速度、车轮动载,并满足悬架动挠度和阻尼系数变化范围的约束,同时对车辆载荷变化、悬架元件参数变化等引起的模型误差具有自适应能力.将广义预测控制(GPC)应用到车辆半主动悬架控制中,提出了车辆半主动悬架一种新的自适应预测控制算法...

| Abstract: | The ride comfort and road holding of vehicle can be obviously improved by using the semi-active suspension.With the constraint of suspension travel and damping coefficient variance,a control algorithm is used to dynamically optimize the vibration acceleration and wheel dynamic load according to the variance of road irregularity and vehicle velocity.The optimal control law is adaptive to the model error caused by the vehicle load variance,variance of suspension component,etc.The generalized predictive control(GPC) is used for vehicle semi-active suspension,which utilized model prediction,rolling optimization,and feedback compensation to optimize the objective function.Simulation results show that the resulting system can provide better control performance. |
