✦ Synopsis

A dascrete time adaptive control system was apphed to the steam temperature control of a boder for electric power generatmn In the system, the adaptive controllers are installed m parallel with the conventmnal PID controllers for superheated and reheated steam temperatures The plant dynarmcs was described with polynormals whose parameters are adaptively estimated from the plant data The adaptive control signals are synthesazed on the basis of the estimated parameters so as to aclueve the specified control objective The system was apphed to a 375MW plant and found to reahze far better control performance than the conventional PID control system Keywords.
