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.
