| 摘 要： | 为改善汽车乘坐舒适性和操作性，研究1／4汽车主动悬架系统的离散最优控制问题，给出汽车主动悬架系统的离散化模型，并通过引入路面扰动补偿向量，给出悬架系统的有限时域前馈反馈最优控制律．通过求解矩阵微分方程得到扰动补偿向量．该控制律容易实现，对由路面引起的振动有明显的抑制作用．

| Abstract: | In order to improve vehicle comfort and interoperability,the discrete-time optimal control of vehicle active suspension systems is considered,and quarter-car model with active suspension system is presented,and also the finite time-domain feed-forward and feedback optimal control law is designed with road surface disturbance compensation vector which can be obtained by solving matrix difference equations.The control design method is easy to implement for reducing vibration came from road. |
