Abstract :
A set-stabilizing constrained state feedback controller for a class of nonlinear positive systems is presented. The controller is applied to stabilization of a gas-lifted oil well, and simulations using a rigorous multi-phase flow simulator (OLGA®2000) illustrates the use of the controller.
