Paper Abstract

In order to realize adaptive control of nonlinear big-lagged water location control system of drum boiler in thermal power plant, based on dynamic property analysis of the water supply course, a combination hybrid adaptive controller is designed in this paper. It includes a few hybrid adaptive controllers that parallel to work, the control signal is obtained by weighting the output signals of the few controllers, at same time, the method choosing weighed coefficients of the combination hybrid adaptive controllers is presented. Theoretical analysis and experiment result show the project is effective to solve inner disturbance, big-lag and pretense water location of the water location control system, and has quick adaptability and strong robustness. The results show that efficiency prospects for its further applications in power plant.
