探讨了一类具有时滞的不确定性中立型 Lurie 控制系统的稳定性问题。通过构造合适的 Lyapunov泛函，利用 Schur 补引理、S-过程和相应的矩阵理论，以矩阵不等式形式给出系统鲁棒绝对稳定的若干时滞相关充分条件，改进了时滞不依赖条件的保守性。

In this paper,the problem of the stability for a class of the neutral Lurie indirect control systems with time-varying construction uncertainty were discussed.By introducing the Lyapunov function-al,and by the method of the lemma Schur and the method of S-procedure and the corresponding matrix theory,the delay-dependent stability sufficient conditions for all admissible uncertainties of the neutral Lurie system are given via linear matrix inequalities (LMIs).The conclusion improved the delay independ-ent criteria.
