Design of discrete time fuzzy sliding mode observer in networked control

For solving the problem of network induced delay and the measuring difficulty of control state monitoring in Networked Control Systems, a discrete fuzzy sliding mode oberserver(DFSMO) is designed in the paper. DFSMO is robust despite the presence of bounded uncertainties. Discrete time sliding mode controller base of the DFSMO is designed for a type of NCS. The simulation results show that the method is effective.
