Abstract :
In this paper, we studied fault detection problem for a class of linear networked control systems (NCSs) with time delays and packet losses. A T-S fuzzy model is employed to represent a NCSs with time delays and packet losses. Attention is focused on the design of fault diction observer. Using linear matrix inequalities (LMIs) and Lyapunov function technology, sufficient conditions for existence of such observer is established. At last, the simulation experiment is used to test the feasibility.
