In this paper, the delay-distribution-dependent stability is derived for the stochastic genetic regulatory networks (GRNs) with a finite set delay characterization and interval parameter uncertainties. One important feature of the obtained results here is that the time-varying delays are assumed to be random and the sum of the occurrence probabilities of the delays is assumed to be 1. By employing a new Lyapunov-Krasovskii functional dependent on auxiliary delay parameters which allow the time-varying delays to be not differentiable, less conservative mean-square stochastic stability criteria are obtained. Finally, two examples are given to illustrate the effectiveness and superiority of the derived results.
本文针对具有有限时滞特征和区间参数不确定性的随机基因调控网络(GRN),推导了时滞分布相关稳定性。这里得到的结果的一个重要特点是,假设时变时滞是随机的,并且时滞的发生概率之和假设为 1。通过采用一个新的依赖于辅助时滞参数的 Lyapunov-Krasovskii 泛函,允许时变时滞不连续,得到了更保守的均方随机稳定性准则。最后,给出了两个实例来说明所得到的结果的有效性和优越性。
