Modelling, simulation and control design for large and heavy manipulators

An increasing need for automated or partly automated sequences of operation in building industry, agriculture, forestry, mining, scrap yards or other working fields with rough and unstructured environment requires machines, cranes, excavators or manipulators which are able to operate autonomously or operator-assisted under rapidly changing working conditions. In this paper, the modelling, simulation and control design of newly projected large, and mobile heavy manipulators which are typical examples of mechatronic systems will be presented. The various techniques are demonstrated by three different examples related to industrial projects.
