Automatic Realization of Human Experience for Controlling Variable-Pressure Boilers

Abstract

Control of thermal power plants is very difficult because of their nonlinearity and interferences. Control methodology, controllers and tuning of parameters in the controller are astringent for a long time accumulation of experiences. The present controllers can be achieved sufficient control performances. However, the tuning of the parameters in the controllers is complicated and their determination is based on the skilled humans' experiences and intuitions. In this paper, automatic realization of the determination of the parameters is proposed based on the nonlinear separation control. By using the proposed automatic determination, the complicated tuning of the parameters is not necessary and the improvement of the control performances is achieved. The effectiveness of the proposed method is evaluated by a simulation study.
