Özet: This paper is focused on digital dynamic pulse-frequency modulation (DPFM) control systems that can be implemented on a microcontroller. We describe a structure of a discrete nonlinear closed-loop system that is equivalent to DPFM. A general-case model of a digital modulator of l-th order is obtained and an example of implementation and performance of an electric drive control system is presented. Our simulation experiments demonstrate that our nonlinear control system offers adequate representation of the digital dynamic pulse-frequency modulator and has advantages compared to previously developed solutions. Future work in this area can be conducted in the field of mathematical modeling of the systems in the form of functional discrete-time Volterra series and their linear approximations. The latter can be used to study dynamic accuracy, and also to perform synthesis of digital control systems of this class.
