Timing problems in distributed control

The DICOSMOS (Distributed Control of Safety Critical Motion Systems) project started in 1993 and was from the beginning a cooperation between Mechatronics Lab at KTH, Computer Engineering at CTH and Automatic Control at LTH. The aim of DICOSMOS is to develop theory and methods to support the design of safety critical control applications. The scope is rather wide and a number of other projects within the Mechatronics Lab have been subsequent spin-offs. Problem formulations for DICOSMOS presented at a seminar held in October 1998 are found in [Törngren and Sanfridson, 1998]. The project has always been sponsored by NUTEK and from 1999 it is also financed by VTD, Volvo technological development. When VTD entered the project a case study was initiated. The case study is a substantial part of the DICOSMOS project and a true cooperation, in which the authors of paper B and related publications, come together and do research at VTD. The aim of the case study matches the aim of DICOSMOS and gives an opportunity for a more active cooperation between the technical institutes and industry. From a technological point of view, the case study gives a good commercial object to study. By doing this, the intention is that the research will be more directed towards problems and phenomena with a stronger industrial bearing.
