Simulation of MIT rule-based adaptive controller of a power plant superheater

Abstract

MIT rule is one of the basic techniques of adaptive control. It can be embedded into a general scheme of circuit with MRAC structure (reference adaptive controller). This paper deals with simulation of MRAC by use of MIT rule for a superheater which is a crucial part of a coal-fired power plant. A superheater has been chosen as a typical practical real plant with time-variant parameters and thus suitable to be controlled by adaptive control mechanism. The paper gives a comparison of adaptive control with MRAC and original PID control currently implemented in a chosen output superheater in Detmarovice power plant. Matlab&Simulink environment is used for a simulation of the control circuit described in this paper. © 2012 Springer-Verlag GmbH Berlin Heidelberg.
