document: Stabilization of positive systems with first integrals Positive systems possessing first integrals are considered . These systems frequently occur in applications . The paper is devoted to two stabilization problems . The first is concerned with the design of feedbacks to stabilize a given level set . Secondly , it is shown that the same feedback allows us to globally stabilize an equilibrium point if it is asymptotically stable with respect to initial conditions in its level set . Two examples are provided and the results are compared with those in the literature
