摘要

本文研究了一类非线性奇异系统的预定义时间自适应鲁棒控制问题。根据非线性奇异系统的结构特性，我们首先通过适当的状态反馈建立耗散形式的奇异系统，然后将其转化为等效的非线性微分代数形式，最后得到严格耗散的微分代数系统，并应用它得到稳定性结果。在此基础上，设计了一个具有外部干扰和不确定性的预定义时间自适应鲁棒控制器。最后，将结果应用于非线性奇异电路系统，并通过对非线性电路系统的仿真验证其有效性。

Predefined-time adaptive robust control of a class of nonlinear singular systems

In this paper, the predefined-time adaptive robust control problem of a class of nonlinear singular systems is studied. Based on the structural properties of the nonlinear singular systems, we first develop a singular system in dissipative form via an appropriate state feedback, then transform it into an equivalent nonlinear differential-algebraic form, finally we obtain a strictly dissipative differential-algebraic system and apply it to obtain the stability results. Based on this, a predefined-time adaptive robust controller is designed with external disturbances and uncertainty. Finally, the results are applied to the nonlinear singular circuit system, and the effectiveness is verified through simulations conducted on the nonlinear circuit system.

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."
