摘　　要：研究了有多个执行机构的多滞后中立型直接和间接Lurie控制系统的绝对稳定性,借助于Lyapunov泛函构造方法,给出了关于Lyapunov泛函中正定矩阵和积分项参数的线性矩阵不等式(LM I)的稳定性判别准则,且与时滞量的大小无关。最后举例说明了本文结果的有效性.In this paper, the abolute stability of a neutral Lurie control systems with multiple delays is discussed. By the method of Lyapunov functional, sufficient criteria are obtained, which are equivalent to the solvability of LMIs on the positive definite matrix and the coefficients of integral terms in the Lyapunov functional, and it is independent of time delays. Finally, two concise examples are provided to illustrate the effectiveness of the presented conclusions.
