【 摘 要 】

The deaerator control system with multiple actuators of main and vice valves was described. An improved control strategy was proposed in order to solve the problems occurred in this type control systems. Especially, the newly tacking loop was designed to satisfy no disturbance switching of the control system. Furthermore, the control algorithm expressed in this paper was confirmed by the rigorous verification of three hypotheses. Thus the no disturbance switching and system stability could be achieved by this control algorithm proposed in this paper. Finally, the control algorithm was applied in the deaerator level control system and condensation water head pressure control system. Fluctuation of the main/assistant regulating valve command was resolved thoroughly. The operation results indicate that the no disturbance switching and superior control performance are achieved after the application of the control algorithm.
