“…Such a stationary coordinate system associated with the stator makes a relatively simple iterative simulation of a line-to-line fault possible. Because of this, the next iteration can be determined for each iteration from the previous moment by making vector composition of the positive and opposite components of the simulated machine (Solodkiy et al, 2018). In the case of an induction motor, a different coordinate system rotating with constant or variable speed rigidly connected with the rotor causes a significant complication of equations and difficulty of analysis.…”

The paper presents research findings in the modelling and optimization of dynamic parameters of mechatronic systems with an induction motor. A mathematical model was developed to analyze currents in dynamic states of squirrel-cage rotors in the case of a line-to-line fault. The findings were verified experimentally using calculations for a 1.5 kW three-phase induction motor. The equations for a stationary 0x, 0y coordinate system relating to the stator were derived. The set of design variables selected in the optimization process contained parameters describing design features of the gear shafts and control units settings.

“…The main disadvantage of vector control systems for AC electric drives is their sensitivity to variations in the parameters of asynchronous machines (AM) [1][2]. The main parametric disturbances in such systems are changes in the active resistances of the stator and rotor windings AM due to their heating [3][4] or inaccuracies in setting the parameters [5][6]. Against this background, the conditions of field orientation are violated, as a result of which the Rybalka О. О, 2021…”

The article examines the quality indicators of information support of the process of observing the flux linkageof the rotor of an induction motor in vector control systems under the conditions of the action of parametric disturbances.This line of research is in-tended to provide a solution to the problem of building a high-quality information control system for an asynchronous electric drive, which eliminates the high sensitivity to deviations inthe parameters of the control object during its operation.First of all, this refers to temperature changes in the active resistances of the stator and rotor. The obtaining information about the rotor flux linkage is as-signed to the observer, which consists of four circuits.In each of the four circuits of the observation system model, two correction signals of thenon-agreementof the stator currents of the asynchronous machine and the observer are introduced through the weighting coefficients. The full vector of correcting feedbacksof the observation system contains in this case eight coefficients. The application of the principles of modal control to determine their numerical values leads to unwieldy equations. The problem is solved more elegant using the direct Lyapunov's method, which makes it possible to determine the possible structure of an observation in-formation system that is stable under parametric disturbances. The numerical values of a part of the coefficients of correcting feed-backs are obtained by the way ofthe analysis of the quadratic form of the total time-respect derivative of the Lyapunov'sfunction of the synthesized information system. To determine the optimal ranges of variation of the remaining coefficients, numerical methods were used to calculate the roots ofthe characteristic equation of a closed-circuit observation system. Thus, the idea of the studyis to use the largest number of correcting feedbacks in the structure of the observation information system and to select their values using the direct Lyapunov's method and numerical methods to ensure its low sensitivity to deviations of the parameters of an asynchronous machine.
