DESIGN OF THE DOUBLE-LOOP NETWORKED CONTROL SYSTEM WITH DIFFERENT SAMPLING RATE BASED ON SMITH PREDICTOR
Journal Title: Topics in Intelligent Computing and Industry Design (ICID) - Year 2017, Vol 1, Issue 2
Abstract
The double-loop networked control system with different sampling rate is investigated in this paper. In order to overcome the effect of network-induced time delay, the design methods based on conventional Smith predictor and modified Smith predictor are discussed. Simulation results based on Matlab/Simulink show that the dynamic characteristics of the system are improved due to the network-induced delay compensation, and the disturbance is restrained effectively. For the system of which the network-induced delay is random and difficult to accurately predict, the control effect of the method with modified Smith predictor is superior to the conventional Smith predictor when certain design conditions are satisfied.
