N2 - In this paper, a dynamic surface control (DSC) strategy for discrete-time strict-feedback multiple-input-multiple-output systems is proposed. State variables are estimated by Luenberger observer using latest outputs received in controller. The control signals, bearing the same time-stamps as the target system, are constructed based on DSC methodologies. The control mechanism also considers the network-induced time-varying delays, packet drops and disorder; these parameters are systematically stacked into the network and transmitted into an actuator where the control function is performed. In order to establish all the design parameters, a simplified methodology of utilising linear matrix inequality and homotopy algorithm is proposed. The simulation results prove that the proposed method is effective.
