【摘要】 利用描述系统方法对状态空间系统的H∞性能进行分析,得到了一个新的界实准则的线性矩阵不等式表示.该表示所具有的分离结构在分析多面体不确定系统的鲁棒性能时,可以有效地减少分析过程的保守性.与存在的同类结果相比,克服了一些理论和数值计算上的不足.两个数值例子说明了该方法的有效性.更多还原

【Abstract】 An improved LMI representation for bounded real criterion is derived by em-ploying a descriptor system approach. Due to its decoupling property between system matrices and Lyapunov matrices, the new criterion can reduce conservatism inherent in robust performance analysis of systems with convex polytope-type uncertainty. The re-sults exhibit some favorable features in computation through two numerical examples.更多还原
