Model-reference adaptive schemes are usually designed on the assumption that the structure of the plant transfer function is known, only the parameter values being uncertain. In the paper, the stability properties of such systems are studied when the plant can only be approximately represented by a model of the type assumed, i.e. when its transfer function does not belong to the class for which exact matching with the reference model can be achieved.
