Abstract :
Dynamic characteristic of supercritical unit is complex. Its control technology is an important research task. This paper presents a mathematical model of coordinated control system controlled objects. For control characteristic of supercritical unit, design a generalized intelligent coordinated control system which made up of classical control, modern control, intelligence control and special measure technique. System control strategy was described and a sufficient condition for the stability of the system was shown. The engineering application indicates that generalized intelligent coordinated control system which fused of various control methods can improve load response rate of supercritical unit and strong steady robustness.
