摘　　要：车辆的悬架系统对于其舒适性和操纵稳定性都起着关键作用。随着计算机技术和液压伺服元件的发展，出现了主动和半主动悬架系统，在其控制策略上具有二次型性能指标的最优控制方法比较成熟。通过建立系统的数学模型和仿真计算，对全状态反馈、有限状态反馈和被动悬架进行了对比分析，表明主动悬架采用的有限状态反馈较全状态反馈有明显优势，是一种比较实用的状态反馈控制方法。The suspension system of the vehicle plays important roles in the ride comfort and maneuverable stability of the vehicle. Along with the development in computer technique and hydraulic servo elements, the full - active and the semi active suspension systems have been raisen. The optimized control method of binary performance index in its control tactics is of more mature consideration. By establishing the systematic mathematical model and imitation calculation method comparative analysis for full condition feedback, limitary condition feedback and the Passive suspension has proved that the limitary condition feedback used for the active suspension is evidently more potent than full condition feedback. Thus, it is known as the usable device for condition feedback.
