摘　　要：为了分析汽车主动悬架最优控制性能函数中加权系数的影响,对某轿车建立了整车七自由度动力学模型,设计了基于随机最优控制策略的状态反馈控制器。通过ADAMS&MATLAB\simulink联合仿真,探讨了性能函数加权系数对悬架控制力的最大幅值及悬架性能的影响,得到了该轿车性能函数中加权系数的变化与主动悬架最优控制力的最大幅值及悬架性能的关系。这为主动悬架最优控制性能函数加权系数的确定提供了参考依据。In order to analyse the influence of weight number of performance function for active suspension, a state feedback controller for the 7-degree-freedoms modal of the automobile based on random optimum control strategy was designed. By ADAMS＆MATLABXsimulink co-simulation, the influence of weight number on maximum value of suspension control force and suspension performance were investigated, which obtained the relation among maximum value of suspension control force, suspension performance and the variety of weight number. The reference to decision of the weight number of performance function by optimum control for Active Suspension could be provided.
