We propose new sufficient linear matrix inequality (LMI) conditions for the stability of uncertain linear systems with static and dynamic output feedbacks. The design of stabilizing controllers is carried out through Euler approximate models where the sampling period appears as a linear variable to be determined. Pole placement is also considered in LMI setting. Examples showing the efficacy of the developed results are presented.
