摘要

针对非线性系统的模糊动态输出反馈控制器，提出了一种智能数字再设计技术。非线性系统采用Takagi-Sugeno模糊模型，带模糊动态输出反馈控制器的模拟闭环系统和数字闭环系统分别采用离散化模型。导出了数字闭环系统稳定和模拟闭环系统矩阵与数字闭环系统矩阵范数距离最小的充分条件。它的充分条件用线性矩阵不等式表示。最后，通过数值算例验证了该方法的有效性。

Intelligent digital redesign for fuzzy systems with the fuzzy dynamic output-feedback controller

This paper presents a intelligent digital redesign technique for the fuzzy dynamic output-feedback controller of the nonlinear system. A Takagi-Sugeno fuzzy model is adopted for the nonlinear system and the discretized models of the analog and digital closed-loop system with fuzzy dynamic output-feedback controllers, respectively. Sufficient conditions are derived for both the stabilization of the digital closed-loop system and minimization of the matrix norm distance between the analog and digital closed-loop system matrices. Its sufficient conditions are formulated in terms of linear matrix inequalities. Finally, a numerical example is provided to verify the effectiveness of the proposed technique.
