Information Technology and Algorithm for Maximizing Accuracy of Angular Position of Platform for Vertical Takeoff and Landing of the UAV

The paper presents research aimed at developing a new algorithm and information technology to achieve high accuracy in the stabilization of the angular position of Stewart platform ensures vertical takeoff and landing of the UAV. The task of stabilizing the angular position of the Stewart platform involves ensuring small angles of its deviation within the horizontal plane under the conditions of nondeterministic external disturbances and factors, specifically in conditions of sea waves, significant fluctuations in wind force and direction, and unevenness of the ground surface. To solve this problem, the synthesis method of an optimal multi-dimensional stabilization system for an object is employed. This object operates under the influence of multi-dimensional stationary random signals, disturbances, and measurement noises. A distinctive feature of information technology and algorithmic software for automation of synthesis stages is an increased accuracy and reliability of calculations, which are achieved through the introduction of a new approach to factorization of polynomial matrices and computational algorithm based on it, improvement of polynomial multiplication algorithms Matlab to reduce the loss of correct significant digits by properly ordering and ranking elementary operands and multiplying fractional-rational matrices to reduce the growth of the order of results based on the use of operations to remove the corresponding poles on the right and left.
