摘要
当汽车悬架的某些参数在较大的范围内变化时,仅通过一个鲁棒控制器有时难以获得令人满意的性能。为此,基于LM I(L inearM atrix Inequalities)优化方法,根据参数变化范围设计多个H∞控制器,并根据实时测得的参数通过内插进行平滑切换,以协调相互冲突的诸性能要求,获得汽车系统的最佳总体性能和在多变的不确定的环境中行驶的鲁棒性。仿真结果表明,该方法能够获得满意的控制性能。
In general, it some parameters of active is beyond possibility suspension changes to acquire high performance by only one robust controller when in an wide span. With the development of technique of electrics and sensor, it becomes possible to measure the parameters in real time. Based on LMI (Linear Matrix Inequalities) optimization method, this paper designs measured parameters in real time to acquire the and to compromise the conflicted requirements. satisfactory using this method. multi controller and switches smoothly by interpolation with the best wholly performance and robustness in uncertain environment Simulation results show that the resulting control performance is
