FURTHER RESULTS ON DELAY-DEPENDENT ROBUST STABILIZATION CONDITIONS OF UNCERTAIN NEUTRAL SYSTEMS

研究带有时不变不确定性的中立型时滞系统的鲁棒镇定/稳定问题.给出了新的镇定/稳定法则.利用改进的Lyapunov泛函,基于线性矩阵不等式方法得到保守性较低的镇定/稳定条件.最后用一个数值算例证明了本文所得到的结论,提交了一些已有结论中的最大的延时.

This paper deals with the problem of stabilization/stability for neutral systems with time-invariant structured uncertainties.A new stabilization/stability scheme is presented.Using a improved Lyapunov functionals,less conservative stabilization/stability conditions are derived for such systems based on linear matrix inequalities(LMI).Numerical examples are provided to show that the proposed results significantly improve the allowed upper bounds of the delay size over some existed ones in the literature.
