“…For carrying out of experimental researches the method of mathematical modeling of an electromagnetic field of objects on the basis of system of Maxwell's equations is chosen. In developing the mathematical model, the following assumptions were made: as a result of the investigation of magnetic DC systems or industrial frequency current, it is assumed that there are no free charges in the system; the field is assumed to be quasistationary, which implies the absence of a delay in the electromagnetic wave in the dielectric; the losses due to hysteresis when the ferromagnetic metals are heated are not taken into account because of their insignificance in comparison with the eddy current losses [15]. The magnetic field equation has the form of …”

Abstract. Modern DC proportional solenoid control systems use current values in magnetizing coils, or specialized sensors for position determination. These methods do not provide the possibility of accurate control and diagnostics, in case of aiming to the miniaturization of finished devices. In this article, it is proposed to use methods of self-sensory identification of the moving element position based on the method of the full-scale-model experiment. The functioning of the method is based on the electromagnet model obtained by the reduced-order model approach. These models have an advantage in the calculation speed in comparison with finite element models and have an advantage in accuracy in comparison with analytical models. Ansys Electronics is used to obtain the model. The electromagnetic control system is proposed. Its model is implemented in the system Matlab Simulink. Synthesis of PID-regulator parameters using Matlab is performed. The results of a study of a control system for a given displacement with the aid of the obtained control system are presented.

“…To obtain ROM from the full FEM models, various methods are used, which are described in detail in [22]. In particular, the ANSYS Electronics system, which performs finite element modeling of objects [15], allows to obtain ROM using the built-in algorithm based on modal decomposition.…”

“…First of all, the accumulation of damage in the form of cracks affects, and also the flexibility of the joints increases. When examining load-bearing systems and monitoring, it is necessary to install sensors not only directly on the loadbearing elements of structures, but also in the zones of connection nodes [2][3][4][5][6][7][8][9][10][11].…”

The use of monitoring techniques during the operation of a building contributes to the study of the stress-strain state of both known and newly developed structural systems. The article discusses the effect of reducing the bending stiffness of reinforced concrete crossbars of high-rise buildings on the overall deformability, which can be monitored by changing the angles of rotation at characteristic points. For the introduction into the model of the calculation based on finite elements of the physical parameters of the stiffness of reinforced concrete bending elements, the function of the change in the shoulder of a pair of forces in the section during the opening of normal cracks is given. Empirical data on changes in the stress unevenness coefficient along the length of the reinforcing bar are used. The calculation is based on the diagrammatic method. The data on the accumulated experience of measuring the angles of rotation of a building with automatic monitoring of buildings are presented. Using the finite element method, the systems were simulated with a decrease in stiffness to 0.4 from the initial one. It is shown that it is possible to select a range of sensors - angle meters - inclinometers. It has been determined that the angle of rotation can be changed up to 1.6 times. The corresponding ranges are defined for two types of frameworks: frame and frame-braced. The nature of the change in the overall stiffness of the building frame as a result of reducing the stiffness of the crossbars is shown. Calculation models based on the finite element method determined the deformation limits of the entire frame as a whole.
