利用增广的Lyapunov泛函结合自由权矩阵方法,对非线性Lurie时滞系统的绝对稳定性问题进行了研究,得到了系统基于线性矩阵不等式(LMI)的具有更低保守性的时滞相关绝对稳定条件。数值实例表明,本方法所得结果优于已有文献中的结果。
The problem of absolute stability of Lurie nonlinear systems with time-delay is investigated by using aug-mented Lyapunov functional combined with the free-weighting matrix approach.Some less conservative delay-dependent stability criteria are obtained and formulated in the form of linear matrix inequalities(LMIs).Numerical example shows that the results obtained are better than the existing results.
