Design of fuzzy and CMAC parallel controller based on GA for main steam pressure in supercharged boiler

The combustion system in supercharged boiler is a complicated multi-variable and complex coupling system. The main steam pressure control system is an important subsystem and has the characteristic of nonlinearity, time-varying and long time-delay, so using the classic control cannot achieve the desired control effect. Evaluating of the characteristics of fuzzy control with quick dynamic response, good robustness and CMAC control with good study capability, good generalization capability, a fuzzy and CMAC parallel controller based on GA is applied in the controller design for main steam pressure control system in supercharged boiler. The simulation results show that the proposed control method has good performance and strong ability of anti jamming.
