The Study of Water Level Fuzzy Control for Supercharged Boiler Drum

Abstract

Based on the application of the fuzzy theory,we designed a state level fuzzy controller for the marine steam power system. Compared with the level PID controller and a single-stage cascade PID level controller about disturbance response, the state level controller is more suitable for marine supercharged boiler level control because of its Smaller overshoot, shorter settling time, and other characteristics.
