The Study of Fuzzy-Pi Control in Supercritical Unit Main Steam Temperature

As for the defects of large-scale main steam temperature surges caused by disproportionate fuel/water ratio, we propose to adopt fuzzy-PI control to the secondary main steam temperature. While traditional PI adjustment is still adopted to the master regulator of the control system, fuzzy controller...

Description
Summary:As for the defects of large-scale main steam temperature surges caused by disproportionate fuel/water ratio, we propose to adopt fuzzy-PI control to the secondary main steam temperature. While traditional PI adjustment is still adopted to the master regulator of the control system, fuzzy controller is applied in the secondary regulator. It turns out that the application of fuzzy controller in manipulating the main steam temperature can result in better adaptation to the changes of load and a reduction in the fluctuation of steam temperatures, hence an improved dynamic performance of the regulated object.
