Passivity-Based Backstepping Control Of A Semi-Batch Reactor

This paper shows that we can use the backstepping method for semi-batch reactor temperature control. The system studied has relative degree higher than one. We show that the feedback system can be written in its error dynamic model form, which is shown to be passive. Input strictly passive feedback controllers render the origins of the passive error dynamics to be globally asymptotically stable. A simulation study shows the application to a semi-batch reactor. Industrial trials are in progress. (C) 2017, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.
