摘要
研究了一类具有双通道时延和丢包的非线性不确定网络控制系统的鲁棒H_(∞)镇定问题。将网络诱导时延和数据丢包对系统的影响,转化为服从Bernoulli二区间分布的等价时延,并考虑系统的不确定性和外部干扰问题,基于T-S模糊系统建立了非线性系统的新模型,通过构造Lyapunov-Krasovkii泛函和线性矩阵不等式方法,给出了使非线性系统鲁棒渐进稳定,并满足H_(∞)性能指标的状态反馈控制器存在的充分条件。最后,用数值仿真结果验证了理论分析方法的可行性和有效性。
The problem of stabilization for robust H_(∞)for a class of nonlinear uncertain networked control systems with network dual-channel induced time delay and packet dropout is studied in this project.The influence of network induced time delay and data packet dropout on the system is transformed into an equivalent delay which obeys the Bernoulli second interval distribution,while considering the uncertainty of the system as well as external interference,a new nonlinear system is established based on the T-S fuzzy system.The model,through the construction of Lyapunov-Krasovkii functional and linear matrix inequality methods,gives sufficient conditions for the existence of a state feedback controller that makes the nonlinear system robust progressively stabilized and satisfies the performance index of H_(∞).In the end,numerical simulation results are used to verify the feasibility and effectiveness of the theoretical analysis method.
