Abstract. An approach to modeling automatic control systems with variable delay using a shift register is proposed. The types of variable delay are analyzed. The combined variable delay arising due to the variable speed and variable length of the signal transmission path is considered. An algorithm for modeling such a delay is proposed taking into account the initial function based on a shift register. The algorithm is implemented in C++ and can be adapted to the code of a microcontroller or a simulation environment block (for example, Matlab/Simulink).

Keywords: automatic control systems with variable delay, simulation, shift register
