Abstract :
In this paper a new model matching condition for multi-input and multi-output delay systems is derived, based on which a model reference adaptive control scheme is proposed. The controller has a structure that is similar to the well known Smith predictor. This explains why the present scheme can cancel time delay effects on the system performance. Due to its adaptation abilities, it cart remove the limitation of the Smith scheme to accurate plant descriptions. The method is illustrated by simulating a fluidized bed combustor for sewage sludge
