Abstract: In the reheat temperature control of the 630MW unit of Guoxin Yangzhou Power Generation Corporation Limited, there was large time delay, nonlinear and drastic disturbance for the controlled object. Using the state variable method, the fuzzy control technique and the intelligent feedforward compensation technique comprehensively, the reheat temperature control strategy was optimized, and the better effects were obtained in practical operation. 

Key words: reheat temperature, supercritical unit, large time delay object, state variables, fuzzy control, intelligent feedforward
