This study develops a passive fault-tolerant control (FTC) method with weak conservatism for the discrete parameter system. For first time, application of (0-1) and symbolic parameters describing system is given. In addition, relationship between domain strategy feasible set discussed. paper mainly discusses significance intersection sets FTC. Moreover, suggestion that can be constructed in abs...

The gas-lifted system has inherent ability to hide the effect of fault hence can inject gas into annulus and oil will still be produced even in presence significant value. This however affects optimal operation could move towards undesirable casing-heading instability. Faults step decrease valves coefficients addition limitation on valve affect flow liquids through system. We detect isolate the...

This paper addresses the problems of robust fault estimation and fault-tolerant control for Takagi–Sugeno (T–S) fuzzy systems with time delays and unknown sensor faults. A fuzzy augmented state and fault observer is designed to achieve the system state and sensor fault estimates simultaneously. Furthermore, based on the information of on-line fault estimates, an observer-based dynamic output fe...
