时域中系统稳定度量测的改进及其应用

Improved Measures of Stability of Structured Perturbation System in State Space Model and Application

本文提出了一种新的线性渐近系统受结构化干扰时系统鲁棒性限幅值的数值计算法,经证实,在大多数情况下,利用合适的误差矩阵U可以改进其限幅值。实例说明了采用本文提出的方法对这一限幅值所作的改进结果。

A new bound on the structured perturbation of an asymptotically stable linear system is proposed which is easy to be determined numerically. It is shown that in most cases the use of the appropriate error matrix U can improve the bound for robust stability. The three examples illustrate the improvement obtained in the bounds using the proposed approach.
