Abstract: The observer for the uncertain fractional-order system with sensor fault and system measurement noise is developed. By using the method of augmented matrix and the invariant property of matrix rank, the uncertain fractional-order system is augmented into the singular fractional-order uncertain system. Based on the linear matrix inequality approach of stability criterion for fractional-order systems, an asymptotic stability criterion of the error dynamic system with fractional-order satisfying 1

Key words: uncertain fractional-order systems, asymptotic stability, linear matrix inequalities(LMIs), observer design, sensor fault, measurement noise
