The model matching design technique is a useful approach to design a control system so that the transfer function of the resultant control system coincides with one of the reference model. Once the desired reference model is assigned, stability of output error between the plant and the reference model is dependent only on poles of controller and reference model. This fact permits limitation of stability of error equation specially when the reference model has slow decaying poles. As to the arguments of improving the stability a double model matching technique provide a striking tool because the error equation is determined to have arbitrary poles independent of poles of the reference model. At the same time controller composed of state feedback and feedforward gains has free vector parameters to prescribe any location of stable region. By any suitable choice of the parameters many different kinds of controller can be constructed as well as holding the model matching condition.
In addition with above characteristics, this paper has two features,
(1) state tracking between the plant and the reference model.
(2) direct derivation of analytical solution of Diophantine Equation and its relation to each gain of controller.
