In this paper, a unified approach for the unknown input observers design for orders between minimum to full is proposed. Solutions of the observer matrices are represented in the parametric form. The procedure is easy and direct. Owing to the free parameter, more control objectives can be achieved. The suitable order of the observer can be chosen according to the practical considerations.
