Abstract

This paper presents real-time application adaptive control concept of a typical industrial plant whose performance is severely affected by disturbances and in particular by changes in the operating point. This is typically the case for large coal fired power plants which canbe treated as multivariable dynamic system.

A short description of the power plant is given. For this power plant, a reduced mathematical model is developed. The results of experimental modelling will be shortly discussed. The conventional control of this power plant is investigated and described. The design of the adaptive model-refence controller used in the power plant for real-time control is presented in theory. Realization of the use of the adaptive control is shown and the results of a three-month installation of a decentralized adaptive control algorithm for electrical power and enthalpy control of a 750 MW power plant are discussed and compared with those of the conventional PID control.
