Research of Smith Monitor AGC Based on Active Disturbance Rejection Control

Abstract:

In response to the characteristics of large time delay, nonlinear, various disturbances in Monitor AGC system for cold rolling mill, a control strategy combining Smith predictor with Active Disturbance Rejection Control (ADRC) is proposed. Approximation ability of Extended State Observer (ESO) to estimate unknown parts of controlled plant model is promoted by model compensated ADRC. Aimed at a 4-high cold rolling mill, simulation analysis for classical Smith predictor monitor AGC and ADRC-Smith predictor Monitor AGC is used. The results indicate that ADRC-Smith predictor Monitor AGC has better performance on robustness and capacity of anti-disturbance.
