An Improvement of the Simple Model Matching Method

In this paper, an outer feedback loop is added to the simple model matching method in order to improve response of a controlled system. We show a condition which the closed loop system added the outer loop coincides with a desired model on specified z. To vanish a steady state error for the step input and the ramp input, a selecting method of parameters of added loop is proposed and its function is proved mathematically. It is shown by numerical simulations that adjusting parameters are also useful to recover stability of the closed loop system
