چکیده
Abstract: This paper proposes an high-gain observer design technique for fault detection in a hydraulic pipeline. A general nonlinear model of a pipeline is first derived based on general conditions. Then the observer is designed based on the general nonlinear model without linearisation. Simulation results show that the proposed technique can detect leaks quickly and accurately, compared with those Kalman-filter based methods.

متن کاملDesign of nonlinear parity approach to fault detection and identification based on Takagi-Sugeno fuzzy model and unknown input observer in nonlinear systems
In this study, a novel fault detection scheme is developed for a class of nonlinear system in the presence of sensor noise. A nonlinear Takagi-Sugeno fuzzy model is implemented to create multiple models. While the T-S fuzzy model is used for only the nonlinear distribution matrix of the fault and measurement signals, a larger category of nonlinear systems is considered. Next, a mapping to decou...
