Abstract

In this paper they are presented some results concerning the Disturbance Decoupling problem in terms of pole placement in the multivariable case. As it is well known, when a feedback control law is chosen to solve a particular problem, usually there exist some fixed poles in the closed-loop system, i.e. closed-loop dynamics that can not be modified because the problem is been solved. This work discusses the Disturbance Decoupling problem by static output feedback in soma particular class of MIMO systems; necessary and sufficient conditions are stated in order to solve the problem in SIMO (single Input -Multi Output) systems and MISO (Multi Input Single Output) systems. The results are very simple to implement using control software like Matlab.
