摘要
对一种车辆主动悬架装置进行了研究。首先对该主动悬架系统进行了分析并建立了该主动悬架系统的数学模型,然后应用线性二次型最优控制方法设计了全状态反馈控制器,以获得最优的主动控制力。对控制器参数的物理意义进行了分析。最后,按主动悬架和被动悬架方式对系统进行了仿真,结果表明:在车辆性能改善方面主动系统优于被动系统。
A vehicle active suspension system was described. First, this system was analyzed and the mathematic model was established, and then all state feedback controller was designed using linear quadratic optimal control method to obtain a optimal control force. The physical meanings of controller parameters were analyzed. Finally, simulations according to active and passive suspensions were done, and the result proves the active one is better.
