Abstract
This paper compares the multi-model gain scheduling (GS) control versus the linear parameter varying (LPV) gain scheduling control. The results of this comparative study is carried out exclusively with PI controllers. Although the simplicity and easiness of the former approach for controlling non-linear industrial plants, its main drawback relies on the impossibility to assure stability and performance for slow parameter variation. On the other hand, the later approach rigorously ensures stability and performance of the control system for any variation (smooth as well as abrupt) of the plant parameters. Finally, both methodologies are tested on a test bench canal.
