作者： Peng Cheng Yanyan Yin Yanqing Liu Feng Pan Key Laboratory of Advanced Process Control for Light Industry (Ministry of Education) School of Internet of Things Jiangnan University School of Electrical Engineering Computing and Mathematical SciencesCurtin University

In this paper, we describe a novel method for constructing fuzzy based event-triggered disturbance rejection control for nonlinear systems. A new fuzzy event based anti-disturbance controller is designed and a reduced order disturbance observer is constructed. Sufficient conditions for the closed loop system to be asymptotically stable under an H∞ performance index are derived. Based on these conditions, the design of a fuzzy event-triggered state feedback controller is formulated and *** results are presented to demonstrate the correctness and effectiveness of our theoretical findings.

第37届中国控制会议

作者： GAO Fang Chen Wenbin She Jinhua Fang Mingxing College of Physics and Electronic Information Anhui Normal University School of Automation Nanjing University of Science and Technology School of Automation China University of Geosciences School of Engineering Tokyo University of Technology

This paper presents a new disturbance rejection scheme that adopts equivalent-input-disturbance（EID） approach for linear descriptor systems. The EID approach is used to estimate the influence of exogenous disturbances on the system. A new control law, which incorporates the EID estimate, is designed to ensure good control performance. A sufficient condition for regular, impulse-free, stable of the control system is derived in terms of linear matrix inequalities（LMI）. And the gains of a state-feedback controller and obserber are designed based on the LMI. A numerical example demonstrates the validity of the method.
