LQG self-tuning control of super-heated steam temperature in power generation

The paper outlines the difficult problem of superheater temperature control. Using protuner data obtained from an actual power station unit, the development of a super-heated steam temperature loop model is presented. The existing classical P/PI solution to this problem is reviewed. Building on previous LQG self-tuning project work, a novel LQG self-tuning multi-loop control design is proposed. The simulation experiments try to replicate the performance of the LQG self-tuner module for the superheater temperature control problem. Conclusions and recommendations close the paper
