本文研究了一类具有给定衰减率的积分时滞系统的指数稳定性。首先,通过仔细研究这方面的文献,通过构造新的Lyapunov-Krasovskii(LK)泛函,建立了一种时滞分解方法,以减少在已有充分条件下的保守性。证明了所提出的充分条件比最近建立的一组充分条件要保守得多。其次,通过分析所考虑的积分时滞系统的特征方程,通过计算一类辅助点时滞系统的最右端零点,得到了该系统稳定的充要条件,并基于该方法建立了易于检验的稳定性判据。数值算例说明了所得结果的有效性。
This paper is concerned with exponential stability of a class of integral delay systems with a prescribed decay rate. First, by carefully exploring the literature on this topic, a delay decomposition approach is established to reduce the conservatism in the existing sufficient conditions by constructing new Lyapunov–Krasovskii (LK) functionals. It is proven that the proposed sufficient conditions are less conservative than a recently established set of sufficient conditions. Second, by analyzing the characteristic equation of the considered integral delay system, necessary and sufficient conditions for the stability are obtained by computing the right-most zeros of a certain auxiliary point-delay linear system, for which stability criteria that are easy to test are also established based on this method. Numerical examples illustrate the effectiveness of the obtained results.
