| 中文摘要:针对具有时变时延的非线性网络化控制系统（NNCS），在离散事件触发的输出通讯机制下，研究了NNCS的保性能控制和H∞鲁棒控制问题。首先，设计NNCS动态输出反馈控制器以得到闭环系统，利用Lyapunov稳定性方法，给出闭环系统在无扰动情况下渐近稳定和保性能的充分条件；其次，在γ次扰动情况下完成系统的H∞鲁棒控制问题；然后，针对系统中出现的输出误差、时延、非线性项等因素的影响，采用变量替换法求解出NNCS动态输出反馈控制器；最后应用Matlab仿真验证所提方法的有效性。 |

| Abstract:For nonlinear networked control systems （NNCS） with time-varying delay，under the output communication mechanism of discrete event triggers，this paper deals with robust control problems and guaranteed cost control problems.First of all， NNCS dynamic output feedback controller is designed for the closed-loop system, Using the Lyapunov stability method，some novel criteria for the asymptotic stability of the closed-loop system and guaranteed cost with no disturbance are given；secondly，the robust control problem withtimes disturbance is proved；then in view of the influence of the factors with system output error，time delayand nonlinear term etc , the NNCS dynamic output feedback controller is designed by using variable substitution method；Finally，a Matlab simulation example illustrates the effectiveness of the method. |
