Information Technology for Identification of the Dynamics Model of Multidimensional Moving Object

The purpose of this paper is the development of a suitable information technology for identifying the model of the dynamics of a multidimensional moving object and the disturbances affecting it during operation, based on the data of vectors of control signals and signals at the output of the object, aimed at increasing the reliability of obtaining calculation results. The Stateflow Matlab application was used to create the information technology of identification. A distinctive feature of information technology is the increased accuracy and reliability of performing calculations, which are achieved due to introduction of a new approach to the factorization of polynomial matrices, improvement of algorithms for multiplying polynomial, fractional-rational matrices, respectively, to reduce the loss of true significant figures due to ordering and ranking of elementary operands. To illustrate the operation of information technology, a multidimensional moving object was chosen a spatial mechanism of parallel kinematic structure based on the Stewart platform. Such mechanisms can be used as simulators for aircraft, such as the A320 and Mi-17-1V, as well as a platform for dynamic testing or calibration of inertial navigation systems. On the basis of the developed information technology of identification for the mechanism based on Stewart platform, its transfer function was determined, as well as the transfer function of the shaping filter, which, in the input signal in the form of white noise, has a random process with given statistical characteristics at the output.
