| 摘 要： | 在系统鲁棒稳定性时域分析中,主要采用Lyapunov直接法,但得出结果的保守性是困忧人们进一步研究的难题之一。本文用Lyapunov直接法分析了线性系统在受到扰动之后的鲁棒稳定性边界,并提出了一种递推算法使估计出的稳定边界向实际边界逼近,因而克服了以前学者得出的结论中普遍存在的保守性问题。

| Abstract: | The main method used in robustness analysis of system stability is Lyapunov direct method in time domain. But the conservitiveness resulted from this method is a key problem that prevents reserchers from further studying. In this paper, the stability robustness bounds of linear system with perturbation is analized by Lyapunov direct method. A iterative algorithm is developed by which the stability bounds can be enlarged to its real bounds after a few iterations and therefore the conservtiveness presented in previously published papers is improved. |
