Optimal Output Control of Linear Regulator Systems with Some Inaccessible States

Abstract

In modern control theory designs require feedback of every stste variable. However, in practice, many chemical process controls only a few output quantities are available, and thus the practical usefulness of optimal control law is limited in this cases. It is necessary to construct estimates inaccessible state variable by direct output measurement.A technique based on a very straight forward method leading to an optimal proportional control in terms of measurable output alone is presented.
