В данной работе рассматривается проблема синтеза системы управления понижающего преобразователя, выпаленного по схеме Buck преобразователь. Предлагаемый метод синтеза регулятора системы управления позволяет учесть при проектировании регулятора колебания и значительные изменения входного и выходного напряжения в процессе стабилизации напряжения. Это достигается за счет использования в алгоритмах расчета параметров регуляторов системы управления линеаризованных моделей объекта управления. В данной работе предлагается использовать линеаризацию рядом Тейлора, но результаты работы позволяют заменить расчет данного параметра на любой другой метод. Также производить анализ использования разработанного непрерывного регулятора и полученных на его основе переоборудованных дискретных регуляторов. На основе проделанной работы был получен обобщённый метод синтеза регулятора для понижающего преобразователя напряжения в непрерывной и дискретной области. Данные регуляторы обладают свойствами адаптивности, которая выражена самоподстройкой коэффициентов регулятора. За счет этого достигается возможность использовании полученной системы управления на широком диапазоне значений входного и выходного напряжения стабилизатора постоянного напряжения.

This paper examines the problem of synthesizing a control system for a buck converter designed according to the Buck converter circuit. The proposed method for synthesizing a control system regulator allows one to take into account, when designing the regulator, oscillations and significant changes in input and output voltage in the process of voltage stabilization. This is achieved through the use of linearized models of the control object in the algorithms for calculating the parameters of the control system regulators. In this work, it is proposed to use Taylor series linearization, but the results of the work make it possible to replace the calculation of this parameter with any other method. Also analyze the use of the developed continuous regulator and the converted discrete regulators obtained on its basis. Based on the work done, a generalized method for synthesizing a regulator for a step-down voltage converter in the continuous and discrete domain was obtained. These regulators have adaptability properties, which is expressed by self-adjustment of the regulator coefficients. Due to this, it is possible to use the resulting control system over a wide range of input and output voltage values of the DC voltage stabilizer.
