Abstract

It is well known that one degree of control structure has some principal limitation. For unstable plants it is not possible to obtain arbitrary transfer function of the whole feedback structure. On the contrary two degree of control structure has no limitation concerning the stability of the plant. The aim of the paper is to show structure limitation for dead beat and LQ control combination.
