主动悬架控制策略介绍【摘要】 悬架是现代汽车最重要的组成之一，悬架结构的选用，不但在很大程度上决定了汽车平顺性的优劣,而且随着汽车速度的提高,对于与行驶速度密切相关的操纵稳定性的影响也越来越大.因此,设计优良的悬架系统,对提高汽车产品质量有着极其重要的意义。悬架系统的讨论由来已久，悬架系统根据控制原理和控制功能可以分为被动、半主动、主动悬架，这些悬架在性能上有很大的差别。由于主动悬架不但能很好地隔离路面振动，而且能控制车身运动,比如启动和制动时的俯仰、转弯时的侧倾等,另外还可以调节车身的高度，提高轿车在恶劣路面的通过性。因此对主动悬架的讨论吸引了一大批工程师对其投入讨论，各种控制方法和作动器也被相继讨论出来，本文主要对这些方法进行一些简介，以供同行参考讨论并对其中的最优控制算法的 LQG 控制器进行探讨。【关键词】 主动悬架 LQG 控制器 单轮模型Introduction of active suspension control strategyAbstract Suspension is one of the most important parts in the modern automobile, the suspension structure, not only largely determines the quality and ride comfort of the vehicle, with the vehicle speed， closely related to the speed of handling and stability and have greater influence。 Therefore， it is very important to design a good suspension system to improve the quality of automotive products。 Suspension system has been studied for a long time. The suspension system can be divided into passive, semi-active and active suspension according to the control principle and control function。 The active suspension can not only well isolated vibration， but also can control the body motion, such as pitching and turning starting and braking when the roll， also can adjust body height， increase the car in bad road through sex。 So the research of active suspension has attracted a large number of engineers for its investment in research， various control methods and actuators have been studied in this paper， some of th...
