A WEIGHTED ALGORITHM OF FUZZY LOGIC ON WATER LEVEL CONTROL OF STEAM GENERATOR

This paper presents the new development of steam generation control system on water level of drum boiler using fuzzy control strategy. The major dynamics of boiler water level include nonlinearities, nonminimum phase behavior, instabilities, time delays, and load disturbances. A weighted algorithm of fuzzy logic strategy is applied to control the steam boiler using GPE(Gaussian partition with evenly spaced midpoints) system. The fuzzy logic controller has been tested in the real plant and results obtained the are given
