Abstract

Based on researching induced delay longer than sampling time of network control system, major problem is due to network communication system model uncertainty that leads to poor control performance. Active disturbance rejection control (ADRC) that based on Uncertainty model is used in this paper, network system and control object are regarded as control object together, the network induced delay be as uncertainties in the controlled object , using extended state observer (ESO) estimating variation of the control system real-timely . then taking advantage of SMITH predictor characteristics that compensate the closed loop system of large delay, improve the ADRC control performance in the network-induced delay further. Matlab/TrueTime network control experiments show that: ADRC-SMITH control method can effectively decrease induced delay of network control systems.
