Abstract

This paper investigates a class of dual loop networked control system with different sampling rate. Smith predictor is used to eliminate the influence of time delay. However, uncertain time-varying delay and different sampling rate in the actual production process make the system with conventional Smith predictor cannot achieve the desired control effect. A modified Smith predictor with regulator is proposed for this kind of networked control system, which can be used to overcome the problems caused by random network delay and various sampling rate. The simulation results based on MATLAB /Simulink show that the proposed model and method are efficient and feasible.
