Repeating Compensation Control System of Steam-gas Temperature Based on Fresh Information Grey Prediction

The repeating compensation control system of steam-gas temperature based on fresh information grey prediction is designed. The grey prediction value can express the state trend of steam-gas temperature, and compensate beforehand to the delay of control system by regulating the input of the control system. Based on the repeating control, the grey prediction controller can ensure the control system by advanced estimating and controlling. Theory analysis and Matlab simulation and operation test show that the control system is effective to resolve the delay of steam-gas temperature control system with strong robustness.
