【摘要】 讨论了一类含变时滞和非线性不确定项的退化中立型系统的鲁棒稳定性,借助于新算子的稳定性,将含变时滞和非线性不确定项的一般中立型系统推广到退化系统中,利用李亚普诺夫方法和线性矩阵不等式给出了一个新的依赖时滞的稳定性判据,相比已有文献具有较低的保守性,最后通过M atlab实现可以验证该判据的有效性和先进性。更多还原

【Abstract】 In the paper Robust stability of degenerate neutral systems with timevarying delay and nonlinear uncertainties was discussed.The neutral system with time-varying delay and nonlinear uncertainties was generalized to the degenerate system in terms of the stability of a new operator.A new delay-dependent stability criterion is presented by Lyapunov method and linear matrix inequalities. It is less conservative than previous methods.Its validity and advancement can be proved by LMI Toolbox in Matlab.更多还原
