Fault-tolerant Output Feedback Control for a Class of Multiple Input Fuzzy Bilinear Systems
نویسندگان
چکیده
A fuzzy fault-tolerant control scheme is proposed for a class of multiple input fuzzy bilinear systems with unmeasurable states. First, a fuzzy detective observer is designed to detect the fault. Based on the developed detective observer, a fuzzy controller is proposed to guarantee the closed-loop system without faults is asymptotically stable. Then, a fuzzy adaptive diagnostic observer is designed to estimate the fault. At last, the fault estimation is used to fault accommodation and a fault-tolerant controller is designed. Based on Lyapunov stability, it is proved that the fault-tolerant controller ensures the closed-loop system with faults is asymptotically stable. An example is provided to show the effectiveness of the proposed method. Copyright © 2014 IFSA Publishing, S. L.

Design 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...
