Research on the Fuzzy Controller of Marine Boiler Drum Level

For classical single loop PID control on marine boiler drum level, the disturbance of steam flux can＇t be solved. A new fuzzy control with fuzzy supervisor method is put forward, in this method, the fuzzy feed-forwa rd control is applied to transact the impact of measurable disturbance signal, and the fuzzy supervisor is used to adjust the proportion of feed-forward control and feed-back control automatically, the control purpose is carried out .Using this method, the double impulse fuzzy control of a marine boiler drum level is realized. According to the computer and experimentation simulation, the results show that this control strategy is ef fective and practical, and this method is feasible.
