Design of multicontrollers for smooth transition between multiple operating regimes

摘要

A multiple-model based controller is designed for transition control when a plant owns several nominal working points on a static curve. The multiple-model controller ensure a smooth transition between two neighboring working points, using an adequate combination of the local controls. When the working points are distant, a supervisor will switch between multi-model controllers so that the trajectory will pass close to intermediate nominal points and gradually reach the final set-point. The local and transition controls validity domains are computed using a method of comparison systems and Vector Norms.
