The unexploring problem of digital control systems analyzes in this article — the impact on their behavior of the limited bit resolution of the hardware and, accordingly, the discrete transfer functions coefficients. The research conducted by the zeros/poles and transient characteristics methods using the mathematical application MATLAB with the package Control System Toolbox and confirmed the relevance of this problem.

The task of providing the required dynamic performance of technical systems is one of the main tasks of the automatic control theory. The synthesis of such systems is carried out based on certain criteria that characterize control quality. Today the most common criterion of the functioning of a dynamic system is an integral quadratic form, which includes not only the coordinates of the object, and also the control influences.

On the basis of a generalized interdisciplinary (interdisciplinary) method of mathema- tical modeling, which is based on modifications of the integral variational principle of Ha- milton-Ostrogradsky, proposed mathematical model of the ultra-high voltage circuit-breaker the main emphasis of which is placed on modeling work the mechanism of moving his contacts.

The paper on the basis of interdisciplinary approaches presented mathematical model of the electric power system, a key element of which is the power line that connected substation “Zakhidnoukrayins’ka” — substation “Vinnyts’ka”. On this basis, the analysis of transients in the power line to single-line performance. Results transients are presented as figures which analyzed.

Наведено математичну модель каскаду: однофазний двопівперіодний
випрямляч з двома вентилями – мотор постійного струму з паралельним збудженням, а також запропоновано метод аналізу перехідних та усталених режимів його роботи.
