Abstract

In this paper the application of a Plug&Control strategy (i.e. toautomatically make the controller work properly after simplyconnecting it in the control architecture, without furtherintervention from the operator) to a typical level control problem is discussed.Experimental results are presented and discussed in order to verify the applicability ofthe strategy in an industrial context. It is concluded thatthe proposed strategy can be implemented successfully for the givenproblem, despite the presence of a nonlinear dynamics.
