The event-triggered fault accommodation problem for a class of nonlinear uncertain systems is considered in this *** control signal transmission from the controller to the system is determined by an event-triggering scheme with relative and constant triggering *** the event-induced control input error and system fault threat,a novel eventtriggered active fault accommodation scheme is designed,which consists of an event-triggered nominal controller for the time period before detecting the occurrence of faults and an adaptive approximation based event-triggered fault accommodation scheme for handling the unknown faults after detecting the occurrence of *** closed-loop stability and inter-event time of the proposed fault accommodation scheme are rigorously *** cases for the fault accommodation design under constant triggering threshold are also *** example is employed to illustrate the effectiveness of the proposed fault accommodation scheme.

Formal Development of Feedback Control System with fault accommodation

Journal of Systems Engineering and Electronics 1998年第4期9卷 22-30页

作者： Gao Jianping & Chen Zongji(Department of Automatic Control,Beijing University of Aeronautics and Astronautics, 100083, P. R. China) Department of Automatic Control Beijing University of Aeronautics and Astronautics. 100083. P. R. China

Control systems are vulnerable to faults in control loops where faults may cause abruptand damaging responses. These systems with fault accommodation are becoming more and moreimportant while appearing in flight control, robots control and nuclear reactor control etc, andcalling for more rigorous development approach. A formal approach is explored in this parer, basedon Extended Duration Calculus, for the development of such kind of systems. A typical exampleof control system with fault accommodation, two-level control system, is used for illstrating ourapproach. Its high level consists of an event-driven supervisor which reeds to the change of plant dueto faults occurrence, and its low level consists of normal controller, reconfigured controller and othercomponents with FDI (fault Detection and Isolation) mechanism. Firstly performance and systemspecifications of the case are formulated in EDC; Then they are refined step wisely into specificationsof the supervisor and the low level components. Finally the whole system performance is verified inEDC framework.

fault detection and accommodation via neural network and variable structure control

引用

控制理论与应用（英文版） 2007年第3期5卷 253-260页

作者： Hao YANG Bin JIANG College of Automation Engineering Nanjing University of Aeronautics and Astronautics Nanjing Jiangsu 210016 China LAGIS-CNRS UMR 8146 Université des Sciences et Technologies de Lille Villeneuve d＇Ascq cedex 59655 France

This paper proposes a novel idea that classifies faults into two different kinds： serious faults and small faults, and treats them with different strategies respectively. A kind of artificial neural network （ANN） is proposed for detecting serious faults, and variable structure （VS） model-following control is constructed for accommodating small faults. The proposed framework takes both advantages of qualitative way and quantitative way of fault detection and accommodation. Moreover, the uncertainty case is investigated and the VS controller is modified. Simulation results of a remotely piloted aircraft with control actuator failures illustrate the performance of the developed algorithm.
