This paper investigates the problem of exponential synchronization control for complex dynamical systems (CDNs) with input saturation. Considering the effects of transmission delay, a memory sampled-data controller is designed. A modified two-sided looped functional is constructed that takes into account the entire sampling period, which includes both current state information and delayed state information. This functional only needs to be positive definite at the sampling instants. Sufficient criteria and the controller design method are provided to ensure the exponential synchronization of CDNs with input saturation under the influence of transmission delay, as well as the estimation of the basin of attraction. Additionally, an optimization algorithm for enlarging the region of attraction is proposed. Finally, a numerical example is presented to verify the effectiveness of the conclusion.
本文研究了具有输入饱和的复杂动态网络(CDN)的指数同步控制问题。考虑到传输延迟的影响,设计了一种记忆采样数据控制器。构造了一种改进的双边循环泛函,该泛函考虑了整个采样周期,包括当前状态信息和延迟状态信息。该泛函仅需在采样时刻正定。提供了充分的准则和控制器设计方法,以确保在传输延迟影响下具有输入饱和的CDN的指数同步,以及吸引域的估计。此外,还提出了一种扩大吸引区域的优化算法。最后,给出了一个数值例子来验证结论的有效性。
