摘要
根据电磁学原理,利用电磁铁作为主动悬架的作动器,构造出电磁作动器的一般结构.在1/4汽车悬架基础上,建立了电磁主动悬架的非线性模型,应用现代控制理论设计了该模型的次优控制器,对模型进行分析、仿真.结果表明,电磁悬架能够实现一般主动悬架的功能,满足车辆平顺性的要求,可以应用于汽车的悬架系统.
Based on electromagnetic theory, electromagnet is used for actuator of active suspension and a general electromagnetic actuator is constructed. On the basis of one-fourth automobile suspension, a nonlinear model is built for electromagnetic active suspension and a sub-optimal controller is designed by applying modern control theory. By analyzing and simulating the model system, the result shows that electromagnetic active suspension can carry out the function of general active suspension, and can cater for the requirements of vehicle ride comfort. It can be applied on suspension system of automobiles.
