Abstract :
This paper presents the newly developed water level control system for drum boiler using the 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 the GPE (Gaussian partition with evenly spaced midpoints) system. The fuzzy logic controller has been tested in a real plant and the results obtained are shown
