Abstract

Principle of construction and structure of an automated control system by underwater towed complex for ocean researchers O.S. Popov, M.V. Burakov Institute of Computer Science, Technical University of Szczecin, Poland State Academy of Aerospace Instrumentation, Saint-Petersburg, Russia I Introduction There are different methods of a self-tuning used in automatic control systems. In the main these are based on either a linear or a piecewise linear mathematical representation of a controlled plant. However not always it is possible to simplify a plant model to that extent. Then there is the only alternative to use a model based on a Software Simulator (SS). By means of the SS may be represented all substantial properties of a plant including such as a nonlinearity in parameters and distributed parameters. But apart from design problems of the SS there are principal difficulties of its application concerned with necessity to test model adequacy and tune the model parameters if necessary
