Process operating mode monitoring: Switching online the right controller

This paper presents a structure which deals with process operating mode mon itoring and allows the control law reconfiguration by switching online the right controller. After a short review of the advances in switching based c ontrol systems during the last decade, we introduce our approach based on t he definition of operating modes of a plant. The control reconfiguration st rategy is achieved by online selection of an adequate controller, in a case of active accommodation. The main contribution lies in settling up the des ign steps of the multicontroller structure and its accurate integration in the operating mode detection and accommodation loop. Simulation results sho w the effectiveness of the operating mode detection and accommodation (OMDA ) structure for which the design steps propose a method to study the asympt otic stability, switching performances improvement, and the tuning of the m ultimodel based detector.
