Estimation of actuator and system faults via an unknown input interval observer for Takagi-Sugeno systems

This paper presents a simultaneous state variables and system and actuator fault estimation, based on an unknown input interval observer design for a discrete-time parametric uncertain Takagi-Sugeno system under actuator fault, with disturbances in the process and measurement noise. The observer des...
