By using a Sylvester equation based parametrization, the minimum norm robust pole assignment problem for linear time-invariant systems is formulated as an unconstrained minimization problem for a suitably chosen cost function. The derived explicit expression of the gradient of the cost function allows the efficient solution of the minimization problem by using powerful gradient search based min...

The state-derivative feedback has received great attention in recent times, for being an alternative to the state feedback and to be capable of, except in the cases where it has at least Artigo submetido em 06/11/2006 (Id.: 00764) Revisado em 19/03/2007, 10/04/2008, 03/03/2009 Aceito sob recomendação do Editor Associado Prof. Liu Hsu one pole in origin, to provide the known pole assignment of a...

In this paper, a zero-pole assignment approach is proposed for disturbance attenuation in dynamic fault detection observer design. The properties of dynamic observers are analysed and it is shown that the poles of a dynamic observer can be shifted and the additional zeros can be assigned arbitrarily. Then, a novel pole-zero assignment approach is proposed and its application to a continuous sys...

Pole placement represents a classical method for controlling finite-dimensional linear time-invariant systems, largely covered in the open literature. Basically, it consists of placing poles closed-loop system some predetermined loci complex plane. This paper discusses extensions this to systems described by delay-differential equations. Among others, finite spectrum assignment (FSA), continuou...
