So we consider applying integrated optimization on the design of a vehicle semi - active suspension system . because traditional design method of vehicle semi - active suspension system always design control parameters following structure parameters and it can not obtain the global optimum performances for the system , this paper presents the method to integrate the structure and control parameters of the semi - active suspension system 对于这种新的优化方法，本文将其应用于汽车半主动悬架的设计上，针对传统半主动悬架先设计其结构参数后设计其控制器，这样易造成系统失去全局最优性能的特点，对汽车半主动悬架系统提出对其结构参数和控制参数进行集成优化的方法。
Several semi - active control algorithms used in the semi - active suspension system with mr dampers are proposed and developed including the " on - off " voltage controller , the continuously linear variable voltage controller , the modulated continuously linear variable voltage controller based on " sky - hook " damping concept and the hybrid controller based on the combination of " sky - hook " damping concept and " ground - hook " damping concept and the fuzzy logic controllers using measurements of the relative displacement between the sprung and unsprung mass or the absolute acceleration of the sprung mass as the input variables of fuzzy logic controllers . the simulation models were prepared in matlab ? simulink ? fuzzy toolbox programs . the experiment setup of the semi - active suspension system with mr dampers in the lab has been designed and developed 根据磁流变阻尼器特性和对悬架系统动力学特性的规律性研究，为磁流变阻尼器设计了基于“天棚”阻尼控制概念的“ on - off ” 、线性连续和修正的线性连续控制策略，基于“地棚”阻尼控制概念的磁流变阻尼线性连续控制策略， “天棚”阻尼和“地棚”阻尼控制概念线性组合起来的磁流变阻尼混合控制策略，根据模糊控制原理设计了以簧载质量和非簧载质量间相对位移或簧载质量加速度分别作为输入变量的模糊逻辑控制器用于磁流变阻尼半主动悬架的智能控制。
Considering the uncertain factors of the suspension system of a vehicle that are from the environment disturb as vehicle running , we bring forward t wo methods to integrate semi - active suspension system in this paper . one is the integrated optimization based on genetic algorithm and lqg control , the other is the integrated optimization based on genetic algorithm and h control 考虑到汽车行驶时具有复杂的外界干扰，使得半主动悬架系统具有很大的不确定性，分别采用遗传算法和lqg控制的集成优化方法，遗传算法和h _控制的集成优化方法，对汽车半主动悬架系统进行仿真和试验研究。
