Extended linear matrix inequality (LMI) conditions, ensuring the stability of commensurate fractional-order linear systems by static-output feedbacks, are given. It is assumed that the system uncertainties are constant and possibly present in all the system matrices. The stabilising static-output feedback is conceived to overcome the system uncertainty and place the poles of the closed-loop system in a well-defined domain that is formed by the intersection of many regions in the complex plane. The control design is formulated as the solution of a set of linear matrix inequality conditions. The validity of the obtained results is testified through an example of a fractional-order system with polytopic uncertainties.
