The purpose of this article is to develop convenient information technology for identifying the model of the dynamics of a multidimensional moving object and disturbances acting on it during operation, according to the vectors of control signals and signals at the output of the object, aimed at increasing the reliability of the calculation results. The Stateflow Matlab application environment was used to create an information technology for identification. A distinctive feature of information technology is the increased accuracy and reliability of computations, which have been achieved through the introduction of a new approach to the processes of factorization of polynomial matrices, improvement of algorithms for multiplication of polynomial, fractional-rational matrices, accordingly, to reduce the loss of significant digits due to ordering and ranking of elementary operands and to reduce the growth of orders of results by using the operations of removing the corresponding poles from the right and left and entering the corresponding zeros on the right and left. During the study, a software and hardware system for collecting experimental data was created to identify the model of the rod dynamics used in the Stuart platform based on LabVIEW using FPGA, SoftMotion, and Real-Time modules. Also in the work, the identification of the model of the dynamics of the rod of the Stewart platform was carried out and its transfer function was determined, as well as the transfer function of the shaping filter, which, with an input signal in the form of white noise, has a random process at the output with specified static characteristics.
