Abstract

This paper deals with the dynamic modelling of a complex electro-hydraulic system. Modelling is based on physical laws and the system knowledge. The main idea is to obtain a simple and reliable model that can be used for controller synthesis and implementation by using the architecture of embedded model control. Simplifications are made by taking as basis the ideas of singular perturbation. A subsequent identification procedure is made in order to acquire some important parameters, required for carrying out a simulation.
