The big capacity boiler superheated steam temperature fuzzy-smith control system

摘要

Because the boiler steam temperature control has strong dynamic delay and inertia and time-varying nonlinear property, the control plan of combining the guidance differential double loop with fuzzy-smith expected compensation is used. Simulation results show that the control system has better performance and stronger adaptive capability than the conventional control plan. It can raise its robustness and has a small capacity for counting. The time suitability of the control system can meet the demands of the operating process.
