Abstract
The KEDDC software package for computer-aided control system design, developed at Ruhr-University, Bochum, F. R. G. is presently applied by the Communications Research Centre (CRC), Ottawa, Canada to the development of control techniques for future large flexible spacecraft in a joint industry, university and government research and development project. The Operational Mobile Communications Satellite (OMSAT) proposed for the mid 1990's featuring a 44m offset-fed antenna, is used as target application. A reduced version of a 146th order high fidelity dynamics model of the satellite serves as a benchmark system. This application is very demanding and forms an important performance benchmark for any software system because the high order of structural models requires the use of highly stable and efficient numerical algorithms. KEDDC has been tested on this problem for more than one year and has performed flawlessly, improving quite considerably the design efficiency as well as the scope of system analysis.
