Networked control has attracted significant amount of interests from both the industry and academic in recent years due to flexible applications and many other advantages.Although various algorithms have been proposed for Networked control systems(NCS)，most control strategies assume that system model is known‘a priori’.Then one ofthe main tasks is to stabilize and compensate the system dynamics due to network-induced delay and data packet loss.The main objective of this paper is however t0.identify a suitable model for the system that is suitable for networked control.A novel networked identification scheme is proposed, where an orthogonal least squares(OLS)algofithrn is applied to select the model structure.In proposed scheme，a discard-packet strategy is developdd which takes into account network-induced delay,data packet out-of-order and data packet loss within one.framework,then a cubic spline interpolation method is used to compensate loss data and improve identification performance.Simulation results demonstrate the effectiveness ofthe proposed scheme.
