The project is to create models of controlled motion of spacecraft, including the influence of essentially flexible structural elements on the dynamics of rotation to improve the accuracy of control, reducing energy consumption. Methods of research are analytical: methods of optimal control, variational methods, asymptotic and numerical: simulation, decision optimization problems, problems of mathematical physics. Methods and algorithms for calculating the dynamic behavior of essentially flexible elements of AES, such as beams, plates and shells, were developed. The mathematical models of the uniaxial angular motion of essentially flexible AES were created. Methods of high-precision control for essentially flexible AES orientation, which realize the developed mathematical models of motion, were investigated. Novelty of the presented models consists in the regarding of the satellite as a deformable beam with the central mass and taking into account the geometric and physical nonlinearity of the elements of such structures. The results are have the interest for specialists in the field of solid mechanics and control of moving objects. Product Description popup.authors Аврамов К.В. Асютін О.Д. Багмут І.О.
