摘要:

研究了含有双随机时延的不确定网络控制系统的鲁棒H状态反馈控制问题。将传感器到控制器和控制器到执行器的网络时延建模为相互独立的连续时间离散状态的马尔可夫随机过程。基于此网络环境,构造时延依赖的控制器,将不确定网络控制系统转化为马尔可夫跳变系统。通过LyapunovKrasovskii泛函方法和新的矩阵不等式技术,给出了系统随机稳定且满足H性能的充分条件,并以矩阵不等式形式给出了相应的控制器设计方法。最后,给出了仿真算例,验证了该方法的有效性。

Abstract:

The problem of robust Hstate feedback control is studied for uncertain networked control systems  with two additive random networkinduced delays. Both sensor to controller delay and controller to actuator  delay are taken into consideration. The networkinduced delays are modeled as two continuestime discrete states Markov chains which are mutually independent. The uncertain networked control system is converted to a Markovian jump linear system with two additive random delays. By using the LyapunovKrasovskii functional method and a new technique of inequality, the sufficient conditions on stochastic stability and Hperformance for the uncertain networked control system are given. The corresponding controller design methods are proposed in terms of linear matrix inequality. Finally, an illustrative example is provided to demonstrate the effectiveness of the proposed method.
