New Generation of Automatic Control Systems for WIG-craft

An accident-free flight at very low altitude over the disturbed sea surface and also marine landing and take-off requires the application of the special methods and means of motion control which are able to solve the corresponding specific problems. Methods of stability provision and solving some other problems of WIG flight by means of automatic control are analyzed. The requirements for motion control systems are reviewed and the criteria for their improvement are given. The statement of the main problems of equipment and software design for flight control at small altitude above the disturbed surface is performed. The aim of investigation is to define the way for operational performance improvement of the vehicles of advanced design. A promising way is by implementation of modern navigation and motion control systems. The experience and achievements in this field of high technology are described. Probable areas of the most effective application of vehicles with such equipment are indicated.
