The article discusses in detail the issue of building modern digital control systems of electric drives, taking into account the specific impact of temporal sampling on the operation of such systems. The emphasis is on the analysis of the process of transformation of continuous dynamic systems into digital form, since this stage is the key to the transition from classic analog control methods to new digital technologies. An important aspect of the study was to take into account the impact of the selected sampization period, because it directly determines the level of accuracy of signal reproduction, affects the efficiency of the actuator.

To describe the behavior of the system, a mathematical model of digital control was created, which is based on the use of impulse transmitting functions and Z-translating apparatus. On the basis of the resulting model, a method of synthesis of a digital regulator was developed, which takes into account the features of a specific control object, technical restrictions on the implementation of algorithms and the need to achieve the given dynamic characteristics.

The proposed approach is not limited to theoretical layout, since its effectiveness is confirmed by the results of computer simulation. Studies have shown that the synthesized regulator provides adequacy of the mathematical model and reproduces the desired behavior of the system with high accuracy. The results of the modeling showed that the use of such a technique allows to improve the reliability and quality of operation of modern electric drives, expanding the possibilities of their use in various fields of industry and automated complexes. The results obtained are not only theoretical but also practical, as they open up prospects for further improvement of digital control systems.
