摘要

本文研究了一类Takagi-Sugeno模糊奇异系统的有限时间镇定和有限时间H∞控制问题，提出了一种有限时间H∞模糊控制器，使系统能够应对外部干扰，闭环系统状态收敛到平衡点。在设计控制器之前，先讨论了Takagi-Sugeno模糊奇异系统的脉冲可控性。然后，设计了有限时间H∞模糊控制器，并用线性矩阵不等式表示了Takagi-Sugeno模糊奇异系统的有限时间镇定条件。最后，对一个非线性奇异系统的仿真结果表明，所设计的控制器对外部干扰具有良好的抑制效果，闭环系统状态在有限时间T收敛到平衡点，并在T之后保持在平衡点。

Finite-time H_∞ control for a classof Takagi–Sugeno fuzzy singular systems

This article studies the finite-time stabilization and finite-time H ∞ control problems for a class of Takagi–Sugeno fuzzy singular systems and proposes a finite-time H ∞ fuzzy controller to enable the system to cope with external disturbances, and the closed-loop system state converges to the equilibrium point. Before designing the controller, impulse controllability of the Takagi–Sugeno fuzzy singular system is discussed. Then, a finite-time H ∞ fuzzy controller is designed, and the finite-time stabilization conditions of the Takagi–Sugeno fuzzy singular system are expressed by linear matrix inequality. Finally, the simulation outcomes of a nonlinear singular system demonstrate that the designed controller has a good suppression effect on external disturbances, and the closed-loop system state converges to the equilibrium point in finite-time T and remains at the equilibrium point after T.

期刊介绍： Systems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
