摘要
研究了具有时不变不确定性的中立型系统的鲁棒镇定/稳定问题。给出了新的镇定/稳定法则。利用改进的Lyapunov泛函,得到了这类系统基于线性矩阵不等式的保守性较低的镇定/稳定条件。最后,用几个例子证明了本文所得到的结果要比现存的结果得到了提高。
This note deals with the problem of with time-invariant structured uncertainties. A stabilization/stability for neutral systems new stabilization/stability scheme was proposed. Using an improved Lyapunov functional, less conservative stabilization/stability conditions were derived for such systems based on linear matrix inequalities （LMI）. Numerical examples were provided to show that the propose results significantly improved the allowed upper bounds of the delay size over some existed ones in the literature.
