Stochastic Stabilization Design of Discrete-Time Markov Jump Systems with Time-Varying Delays

中文摘要英文摘要

研究了具有部分未知转移概率的2个独立马尔科夫(Markov)链的时变时滞离散Markov跳变系统的状态反馈控制器设计问题.首先,为避免时变时滞依赖型非凸多项式的出现,引入增广状态相关向量和扩展自由权矩阵零等式以提高稳定性分析的效率,降低稳定性判据的保守性;其次,考虑部分未知转移概率矩阵的性质,通过构造改进的Lyapunov-Krasovskii泛函,并综合利用基于辅助函数的求和不等式和倒凸不等式,建立了所考虑系统随机稳定的低保守性充分条件;此外,利用线性矩阵不等式、Finsler引理和矩阵代换法设计出系统状态反馈控制增益;最后,通过数值仿真对比实验验证了所提出控制设计方案的可行性和有效性.

This paper studies the problem of designing a state feedback controller for the time-varying de-layed discrete Markov jump system with two independent Markov chains and partially unknown transition probabilities.Firstly,in order to avoid the occurrence of time-varying delayed dependent non-convex poly-nomials,the augmented state correlation vector and the zero equation of the extended free weight matrix are introduced to improve the efficiency of stability analysis and reduce the conservativeness of stability criteria.Secondly,concerning the properties of the partially unknown transition probability matrix,a less conservative sufficient condition for the stochastic stability of the considered system is established by con-structing improved Lyapunov-Krasovskii functionals and by utilizing the auxiliary-function-based sum ine-quality as well as the reciprocally convex combination inequality.In addition,the state feedback controller gains of the considered system are designed by linear matrix inequalities,Finsler lemma and matrix substi-tution method.Finally,the feasibility and effectiveness of the proposed control design scheme are verified through a comparative numerical simulation example.
