摘要/Abstract

摘要： 为了进一步提高车辆乘坐舒适性，同时有效地解决线性二次型高斯最优控制器在实际应用中存在的待测状态变量多、路面参数获取困难、应用成本高等问题，基于1/4车辆座椅主动悬架系统模型，设计了一种基于次优控制理论的车辆座椅主动悬架，并对不同待测状态变量下的车辆座椅次优主动悬架的性能进行了探讨，进而得到了基于次优控制理论的车辆座椅主动悬架的最优控制策略.在此基础上，通过与传统车辆座椅被动悬架、最优控制主动悬架进行对比分析，对所设计的座椅次优控制主动悬架的应用效果进行了验证，为车辆座椅主动悬架系统设计提供了一种新的技术思路.

Abstract: In order to improve the ride comfort of vehicles, and effectively solve the problems of linear quadratic Gaussian optimal controller in practical application, such as many state variables to be mea-sured, difficulty in obtaining road parameters, and high application cost, a vehicle seat active suspension based on suboptimal control theory is designed according to 1/4 vehicle seat active suspension system model, and the performance of the vehicle seat suboptimal active suspension under different state variables is discussed. An optimal control strategy of vehicle seat active suspension based on suboptimal control theory is obtained. The reliability of the designed vehicle seat suboptimal control active suspension is verified by comparing with the traditional vehicle seat passive suspension and optimal control active suspension.
