本研究探讨具参数不确定性、时变延迟及资料封包遗失之非线性系统之镇定问题。区间型2 Takagi-Sugeno模糊模型表示的非线性系统的参数不确定性。系统的上、下隶属度函数使得参数不确定性能够被有效地捕获。为了提高设计的灵活性，所提出的状态反馈控制器不共享模型的前提隶属函数。与现有的大多数结果不同，本研究同时考虑了非线性控制系统中的参数不确定性，时变时滞和数据包丢失。一个新的有限和不等式，其中包括著名的不等式作为特殊情况下，推导出新的稳定性条件的线性矩阵不等式的形式。几个仿真例子被用来证明所提出的方法的有效性。
This study explores the stabilization problem of nonlinear systems subject to parameter uncertainties, time-varying delay, and data-packet dropouts. An interval type-2 Takagi-Sugenofuzzy model is employed to represent nonlinear systems subject to parameter uncertainties. The lower and upper membership functions of the system enable parameter uncertainties to be captured effectively. To enhance the flexibility of design, the proposed state feedback controller does not share the premise membership functions of the model. Unlike the majority of existing results, the present study simultaneously considers parameter uncertainties, time-varying delay, and data-packet dropouts in nonlinear control systems. A novel finite-sum inequality that includes well-known inequalities as special cases, is developed to derive new stability conditions in the form of linear matrix inequalities. Several examples of simulation are used to demonstrate the effectiveness of the proposed approach.
