Abstract: An attempt to implement an algorithm based on a microcontroller control system will either tighten the requirements for the speed of the central processor of this system, or result in a catastrophic decrease in the speed of the system and its inability to operate in real-time when trying to obtain the minimum acceptable accuracy of the resource-intensive calculations. The purpose of the research was to conduct a degree of parametric identification of the stability of microprocessor or computer control systems. As a result of the research, it has been established that control microcontrollers created computational delays into the phase-frequency characteristics of closed systems, and the converter on its own was a nonlinear link with a constant transmission coefficient in a certain range, it became necessary to evaluate their effect on the stability of closed systems. As a result of the analysis, it was found that to ensure sufficient stability of the internal contour of the closed system, it is necessary to increase the allowable margins both in phase and in amplitude.
