【Abstract】 Predictive functional control strategy with feedforward compensation f or load fluctuation is provided in superheated steam temperature system. The alg orithm of the strategy is simple, and the strategy is easy to be realized in com puter or decentralized control system(DCS), therefore it has hopeful application prospect. Many computer simulation results show that the advanced control stra tegy has more favorable dynamic characteristic than PID cascade control strategy in superheated steam temperature system, and better load disturbance rejection than PID cascade control strategy and PFC-PID cascade control strategy without f eedforward compensation for load fluctuation.更多还原
