Fault detection and time domain of flight networked control system

The problem of fault detection was studied for flight networked control system with Markov delay and packet dropout. The networked control system with those problems was modeled as discrete Markov jump system. Based on this model, the residual generator was constructed as the observer and the problem of fault detection was transformed to the problem of H_∞ filtering problem. The solvable condition of the fault detection filter and further the solution were derived by using linear matrix inequality techniques. To improve the performance of the fault detection system and enhance the sensitivity to the fault, a time domain optimization approach and it's solution were proposed to deal with the residual evaluation function. A numerical example was provided to illustrate the effectiveness of the proposed approach.
