This paper presents a static output feedback controller design for discrete-time nonlinear systems exactly represented by Takagi-Sugeno models. By introducing past states in the control law as well as in the Lyapunov function, more relaxed results are obtained. Different conditions in terms of linear matrix inequalities are provided. The proposed conditions are less demanding than the ones in the literature. This is illustrated via numerical examples.
本文提出了一种针对离散时间非线性系统的静态输出反馈控制器设计方法,该系统由 Takagi-Sugeno 模型精确表示。通过在控制律和李雅普诺夫函数中引入过去状态,可以得到更宽松的结果。给出了不同的线性矩阵不等式条件。所提出的条件比文献中的条件要求更低。通过数值示例说明了这一点。
