Abstract

Abstract: To effectively control the water level of steam generators(SG), in this paper, the theoretical analysis on SG water level control objects is conducted and a second-order active disturbances rejection control (ADRC) strategy adopting feedforward and feedback control is proposed to address the“false water level” issue. In combination with the SG water level control under two disturbance conditions, i.e. large disturbance and small disturbance, different self-adaptive fuzzy ADRC controllers are designed. Moreover, simulative comparison is carried out between the new designed controllers and the traditional ADRC controllers, which shows that the self-adaptive fuzzy-ADRC control systems outperform the traditional ADRC control systems.

Key words: steam generator, water level control, self-adaptive, fuzzy-ADRC, disturbance
