【Abstract】 The design of observer-based robust fault detection for networked control systems(NCSs)under communication constraints and varying sampling rate is studied.A simple information-scheduling scheme is presented to describe the scheduling approach for system signals in NCSs.Based on such scheme and given sampling method, the design procedure of switching fault detection filter as well as periodical time-varying model for networked control system is given.The simulation results demonstrate the effectiveness of the designed method.更多还原
