Abstract

In a glasshouse heating control loop, usually saturations are inherently present.
When a PI-algorithm is used for an accurate control, an antiwindup procedure has to be employed.
In this paper such a procedure is presented for a typical glasshouse heating control loop, consisting of a master-slave configuration.
