The Technology to Embed the Predictive Control Algorithm into Configuration Control Software at the DCS Level

Abstract:

The development work and proposes the technique to embed the predictive control algorithm into configuration control software at the DCS level. The thesis presents the technique and its application scheme to control CFBB super-heated steam temperature in a thermal power plant. The control scheme includes that the description of controlled plant characters, conventional control scheme analysis and improved control scheme design. It integrates feed-back and feed-forward DMC with DMC-PID cascade control and nonlinear gain-scheduling compensation for actuator. Satisfactory industrial application results show that such a control scheme has enhanced robustness to the complex process, and better control performance has been obtained.
