Abstract

Abstract: The nonlinear action of hybrid PI controllers makes possible to achieve almost none overshot with the smallest rise time possible (for the available input energy) and a settling time almost equal to the rise time. However, all of these nice properties require changes on the control loop. Our contribution is the proposition of a plug-in control action that can be added to the classical linear PI to avoid changes in the hardware, and still achieve the same behavior of a recently introduced adaptive hybrid PI controller. Our proposal is illustrated by real-time level control experiments in a nonlinear reservoir. Performance indexes are presented to evaluate the experimental tests.
