Aerospace Instrument-Making Annotation << Back Recurrent estimation of the angle motion coordinates of flexible objects of aerospace techniques T.V. Yermilova, V.M. Suhanov, A.S. Yermilov, V.G. Borisov The algorithm of the motion coordinates estimation for multifrequency, mechanical oscillating systems, freely moving in space, based on the Kalman method discrete filtration and on the modal-physical form of the identification object description is offered. The methods of mathematical modeling demonstrate the convergence of the synthesized algorithm and split-hair accuracy of the estimation. Some problems of control dynamics of the considered objects are reviewed at the usage of the received estimations in real time.
