Construction of a low parameter and disturbance sensitivity system by a model-following method

Many conventional design techniques can be only applied to ideal controlled objects without parameter variations and disturbances. This paper proposes a new method by which these techniques can be applied to practical objects with parameter variations and disturbances. The principle is to construct a model-following system which makes the practical object output follow the model output and to convert the practical object to the ideal object which has extremely low parameter and disturbance sensitivity.
