In this paper, a decoupling control for a non-minimum phase system is considered from a limiting form of linear optimal regulator problems point of view, and an explicit relationship between the limiting properties and a decoupling control is shown. Moreover, using an appropriate performance index, this paper deals with the new method on the decoupling control to keep out the effect of the natural poles by pole-zero cancellation. The properties of stability and sensitivity are improved by this method. This paper also gives numerical examples to illustrate effectiveness on decoupling control with a limiting form.
