On Fault Detection of NCSs Subject to Limited Communication Capacity
This paper addresses the problem of fault detection filter design for networked control systems (NCS) subject to limited communication capacity and a class of sensor stuck faults. Considering the communication limitations (e.g., measurement quantization, signal transmission delays, and data packet dropouts) and all possible sensor stuck faults, a unified mathematical model is first presented. Based on this framework, a full-order fault detection filter is designed such that the residual system is asymptotically stable with the prescribed attenuation level in the generalized H∞ sense. In order to further improve the detection performance, an optimization algorithm is proposed to minimize the threshold. Finally, a spring-mass-damper system is utilized to show the effectiveness of the proposed method.
