研究一类基于Markov模型的网络控制系统的稳定性和镇定控制器设计问题.针对网络控制系统中受控对象模型的随机切换和通信过程中的丢包问题,利用具有两个独立Markov链的离散时间Markov跳跃系统进行建模.在该Markov跳跃系统模态转移概率矩阵部分元素未知的情况下,充分考虑转移概率的约束条件,给出系统可镇定的充要条件和状态反馈控制器的设计方法.最后通过仿真示例验证了所提出方法的有效性. This paper studies the stability of a kind of networked control system based on Markov model and the design of stabilization controller.Aiming at the problem of random switching of controlled object model and packet loss problem in networked control system by using discrete Markov chain Time Markov jump system, the sufficient and necessary condition for the system to be stabile and the design method of the state feedback controller are given considering the constraint conditions of the transition probability given that the elements of the Markov jump system modal transition probability matrix are unknown. Finally, the simulation results show the effectiveness of the proposed method.
