Identification and Control of an Injection Moulding Machine

Beschreibung

This paper deals with modelling and control of an injection moulding process. During the packing phase the pressure in the mould must follow certain trajectories. First a mathematical model for the packing phase is presented. Therein a characteristic function is needed which depends mainly on the form of the mould. Since the characteristic function is hardly determinable it has to be estimated automatically. This is done with cubic basis splines. The mathematical model turns out to be input to state linearisable resp. differentially flat. So trajectory planning is easily feasible and a flattnes based controller is presented. Since not every state variable can be measured an observer is added.
