摘要
研究一类区间时变时滞线性不确定系统的鲁棒稳定性问题.通过引入增广Lyapunov泛函,结合积分不等式方法,导出了区间时变时滞线性系统的时滞相关鲁棒稳定性新判据.与现有方法不同,该方法不涉及自由权矩阵技术和任何模型变换,减少了理论和计算上的复杂性,而且在估计Lyapunov泛函导数的上界时没有忽略某些有用项.数值算例表明,所提出的判据是有效的,具有更低的保守性.
The robust stability of linear system with interval time-varying delay is investigated.A delay-dependent robust stability criteria for linear system with interval time-varying delay is derived by using an augmented Lyapunov functional combined with the integral inequality approach.Unlike existing methodologies,the proposed approach involves neither freeweighting matrix nor any model transformation,so that it can reduce the complexity both in theory and in computation.And this approach doesn＇t ignore some useful terms when estimating the upper bound of the derivative of Lyapunov functional.Numerical examples show the effectiveness and less conservatism of the proposed criteria.
