Fuzzy Logic Strategy for Boiler Control
动力锅炉燃烧系统的模糊控制策略

This paper presents the new development of the steam generation control system of drum boiler using fuzzy control strategy.The major dynamics of a boiler include nonlinearities nonminimum phase behavior,instabilities,time delays,and load disturbances.Traditional control strategy could not offer satisfactory result.A special subclass of fuzzy inference systems,called the GPE(Gaussian partition with evenly spaced midpoints) systems,is used to control the steam boiler system.The fuzzy logic controller has been tested in the real plant and good results have been obtained.A comparison with conventional control approaches widely used in the plant is performed.
