This paper deals with the problem of fault estimation for linear and nonlinear systems. An adaptive proportional integral observer is designed to estimate both the system state and sensor and actuator faults which can affect the system. The model of the system is first augmented in such a manner that the original sensor faults appear as actuator faults in this new model. The faults are then considered...
This paper deals with the problem of fault detection and identification in noisy systems. A proportional integral observer with unknown inputs is used to reconstruct state and sensors faults. A mathematical transformation is made to conceive an augmented system, in which the initial sensor fault appear as an unknown input. The noise effect on the state and fault estimation errors is also minimized...
This paper treats the problem of an adaptive fuzzy control of continuous nonlinear systems which contain unknown constant parameters in their state space. These systems are represented by Takagi-Sugeno fuzzy model. The quadratic Lyapunov function is used in the stability analysis and the design of fuzzy controllers. A common symmetric positive definite Lyapunov matrix allows us to determine an update...
An approach of internal model controller synthesis for nonlinear systems is proposed in this paper. This approach is based on the multimodel modelling of nonlinear system and the realization of a specific inversion of each model. The inverse realization of each model is necessary in the internal model controller design. The case of a nonlinear system is presented to show the effectiveness of this...
