PREDICTION OF A CONTROLLED MOTION OF FLEXIBLE MARINE-TUGGED OBJECTS

Prediction algorithms for controlled motion of objects with distribute d parameters that are tugged in a fluid (a seismoreceiver cable, a pip e of a mining complex, a boom for the oil flood restriction, etc.) are studied. The control variable here is the radius vector of the object point, attached to a tug system (to a ship or to a self-propelled dev ice, which moves over the sea bottom). The proposed algorithms are bas ed on the numerical solution of a boundary nonlinear problem of an obj ect dynamics (with distributed parameters). An object specification is accounted by the definition of boundary conditions and the distributi on function of its mass characteristics.
