摘　　要：针对具有信号时延的列车网络控制系统,研究其鲁棒稳定性问题.把该系统建模为具有线性时滞的系统模型,基于Lyapunov稳定性理论,以Riccati不等式方程的形式给出了具有信号时延的列车网络控制系统时滞独立鲁棒稳定的充分条件,同时设计了鲁棒控制器,结合数值实例给出相应的仿真结果,仿真结果验证了方法的有效性.Focus on the train networked control systems with signal time delay,the problem of robust stability of train networked control systems is studied.The train networked control systems with signal time delays can be modeled as the linear delay systems based on Lyapunov stability theory,and the conditions of delay-independent robust stability are given by Riccati inequation.A robust controller is also designed,and the simulated result is given through the numerical example,which shows the effectiveness of the proposed method.
