针对一类具有不确定网络诱导区间时滞和非线性干扰的网络控制系统,通过利用一种改进的区间时滞相关的Lyapunov函数以及扩展的Jessen不等式,推导出网络控制系统渐进稳定的充分条件。该方法既未使用模型变换,也没有引入自由权变量。与已有的结果相比,所提出的算法具有更低的保守性和更高的效率。另外,通过数值算例验证了所提出算法的优越性。
By constructing an improved interval-delay-dependent Lyapunov functional and introducing an extended Jessen's inequality, the paper proposed a stability analysis of a class of networked control systems with interval time-varying delay and nonlinearity. Neither free weighting nor model transformation is employed in the derivation of system stability criteria. It is shown that the new criteria can provide less conservative and more efficient results than the existing ones. A numerical example is given to demonstrate the superiority of the proposed method.
