| 摘 要： | 研究一类基于模糊T-S模型的非线性时滞系统鲁棒镇定问题．基于记忆型状态反馈策略，首先给出由T-S模糊模型描述的非线性时滞系统在时滞精确已知情况下的鲁棒镇定准则；然后给出非线性时滞系统在时滞未知情况下的鲁棒自适应控制策略．所设计的控制器可确保闭环系统渐近稳定，且具有良好的可操作性．最后通过仿真实例证明了该方法的正确性和有效性．

| Abstract: | The robust stabilization problem for nonlinear time-delay systems based on fuzzy T-S model is studied. The stabilization criteria for nonlinear time-delay system described by fuzzy T-S model are proposed on (condition) that the time-delay is precisely available via memory state feedback strategy. An adaptive controller is given in the case of unavailable time-delay. The designed controller guarantees the closed-loop system to be asymptotically stable and possesses good operation. Finally, simulation example shows the validity and effectiveness of the proposed method. |
