Adaptive control of main-steam temperature based on quasi-ARMAX model for a super heater system in a thermal power plant

摘要

This paper deals with an adaptive control based on quasi-ARMAX model for main-steam temperature raise of super heater systems in a thermal power plant. In the quasi-ARMAX modeling, it's important to consider some known external input. Then the validity of constructed model is verified, and a nonlinear predictor model is constructed based on its model according to a linear theory. Finally, an adaptive control system for main-steam temperature is designed in a similar way to the linear stochastic control theory.
