Conjunctive model of the invariant control object status

Abstract

Background. At the present stage of development of engineering and technology, the problem of obtaining information in advance about an approaching natural or manmade disaster in order to prevent it or minimize damage from it is becoming increasingly important. Materials and methods. The article provides a description of the conjunctive model of the state invariant of the control object, with the help of which the control of the dynamics of the vibrational activity of the object is carried out. This control is carried out by the information-measuring control system (IMCS) built into the Earth remote sensing system. Results. A description of the conjunctive model of the invariant of the vibration intensity of a geographically distributed object, designed to assess the state of this object, which is carried out by the IMCS, is given. A substantive analysis of the existing vibration measurement methods has been carried out. It has been substantiated that for the implementation of the claimed approach, the method of estimating the intensity of the vibrational process by analyzing the vibrational blurring of the image of the test segment seems to be the most appropriate. It is substantiated that the round shape of the test segment is the most suitable for solving the problem. A description is given of ways to search for the intensity invariant of the vibrational process, if this invariant is formed during the analysis of the image parameters of a round test segment. An equivalent circuit for substitution of a real vibrational process is proposed. The description of the process of formation of disjunctive and conjunctive traces of vibrational blurring of the image of a round mark is given. The method of mathematical modeling shows a direct relationship between the amplitude of the vibrational displacement of the image of the test segment and the area of the vibrational increment of the conjunctive trace of the vibrational blurring of the image of a round mark. A criterion for assessing the intensity of vibration is formulated. Conclusions. As an estimate of the vibration intensity, a value is taken that is directly proportional to such an amplitude of the rectilinear vibrational movement in the plane of the object, at which the relative vibrational increase in the area of the conjunctive trace of the vibrational blurring of the image of a round mark.
