| 摘 要： | 通过对模型频域特性的分析，研究了发动机及前后座椅对车辆模型的影响，提出了一种新的多自由度车辆模型，基于该模型应用LQ理论对主动悬架的控制器进行设计，对基于不同车辆模型设计的不同控制器的控制效果进行比较研究，提出了一种较理想的主动悬架控制策略。

| Abstract: | The current method for solving the problem of active suspension control for a vehicle often uses a quarter car or a half car model. This kind of model is not suitable for practical applications. In this paper, based on considering the influence of factors such as the engine, seat and passengers, a MDOF( multi-degree-of-freedom) model describing the vehicle motion has been set up and a controller for this model is designed by using LQ control theory. Furthermore an appropriate control scheme is selected by testing various performance indexes. |
