State estimation and fault detection for 2-D discrete-time systems

Abstract : This paper presents an observer based sensor fault diagnosis for 2-D systems. Firstly, a state observer is designed by taking into account the measurements in a fixed length sliding window. Secondly, structured residual signals are generated by a bench of finite memory state observers which allow to detect and isolate sensor faults affecting the system. Finally, simulation results are given to illustrate the proposed approach.
