Its control technology is an important research task. This paper presents an mathematical model which associated on coordinated control, feed water and main steam temperature. Adopting observer to estimate coal heat value, and design a synthetic coordinated control system (SCCS) made up of classical control, modern control, intelligence control and special measure technique. The kernel of SCCS is described with block diagram, its main characters are expounded, and the sufficient condition of its stabilization has shown. The project application indicates that the load rate of a 660MW unit is 12MW/min in constant and variable press mode. The system robustness is testified and response rate of supercritical press unit is improved. <br/>KEY WORD: supercritical press; once-through boiler; Boiler-turbine coordinated control system; incremental function observe; <br/>heat value; enthalpy value <br/> </font></p>
