摘要
以转向工况下整车主动悬架系统为研究对象,用线性分式变换理论对悬架参数进行不确定性分析,应用频率加权函数对不确定性系统进行频率加权增广描述,采用H2/H∞鲁棒控制方法,对系统进行仿真分析。仿真结果表明H/H鲁棒控制可以较好地提高悬架系统综合性能。
The active suspension model of full-car vehicle un- der steering condition was created. The parameters uncertainty about suspension was analyzed based on the theory of linear fractional transformation. The uncertain system was described with frequency weighting augment by using frequency weighting function. The H2/ H∞ robust controller was designed and simulation analysis was made by comparison of two kinds suspension. The results showed that the H2/H∞ robust controller could improve the performance of the suspension system.
