Active Disturbance Rejection Control Method With Its Application to DC/DC Converter

This paper investigates the control of DC-DC converter with the help of Active Disturbance Rejection Control (ADRC). The DC-DC converter is an important power electronic equipment used for voltage regulation, but its performance is often influenced by external disturbances. Traditional control approaches, such as PID, are inadequate in handling such disturbances in real-time. To address this challenge, an ADRC-based control approach is applied. The ADRC control approach, particularly through the use of Extended State Observer (ESO), is configured to address and reject disturbances, ensuring accurate output voltage control. In this paper, DC-DC buck converter and boost converter are both applied with ADRC control approach, to analyze the more general situation.
