In this paper, we investigate a problem of exponential state estimation for Markovian jumping genetic regulatory networks with mode-dependent probabilistic time-varying delays. A new type of mode-dependent probabilistic leakage time-varying delay is considered. Given the probability distribution of the time-delays, stochastic variables that satisfying Bernoulli random binary distribution are formulated to produce a new system which includes the information of the probability distribution. Under these circumstances, the state estimator is designed to estimate the true concentration of the mRNA and the protein of the GRNs. Based on Lyapunov-Krasovskii functional that includes new triple integral terms and decomposed integral intervals, delay-distribution-dependent exponential stability criteria are obtained in terms of linear matrix inequalities. Finally, a numerical example is provided to show the usefulness and effectiveness of the obtained results.
在本文中,我们研究了具有模式依赖概率时变延迟的马尔可夫跳跃基因调控网络的指数状态估计问题。考虑了一种新型的模式依赖概率泄漏时变延迟。给定延迟的概率分布,构建满足伯努利随机二元分布的随机变量以产生一个包含概率分布信息的新系统。在这种情况下,设计状态估计器来估计基因调控网络中mRNA和蛋白质的真实浓度。基于包含新的三重积分项和分解积分区间的Lyapunov-Krasovskii泛函,通过线性矩阵不等式得到了依赖延迟分布的指数稳定性准则。最后,给出一个数值例子以说明所得结果的有用性和有效性。
