基于最优控制导弹运输发射车主动悬架研究

Research on Active Suspensions of Some Missile Transporter-Launcher with Optimal Control

针对某导弹运输发射车的四自由度模型,设计了主动悬架控制系统,以满足导弹发射和机动运输状态的整车重要部位处的减振要求。对于发射和机动两种工况,应用最优控制理论设计控制器,并给出了作动器的切换策略。最后对控制系统进行计算机仿真,结果证明比被动悬架有更好的减振性能。

Baaed on a four-freedom model of some missile transporter-launcher,the active suspensions control system is designed for vibration damping of important position of the vehicular missile weapon system whether launching or ma- neuvering states.The optimal control method is applied to design the active suspensions control system for launching and maneuvering states,and the actuator switching strategy is also given.Last,computer simulation results indicate that active control suspensions system have better vibration damping effects than passive suspensions.
