“…The idea of ADRC is to treat all uncertainties and disturbances as a generalized disturbances and to estimate them by Extended State Observer (ESO) (Eker & Özbek, 2021). Then, the control scheme utilizes the uncertainties and disturbances as feedback to reduce undesired signals.…”

This study presents an active disturbance rejection control (ADRC) technique for a boost converter system which is represented with a second - order transfer function. Then, linear active disturbance rejection control (LADRC) technique, wherein a linear extended state observer (LESO) is constructed to estimate both the total disturbance and the system state at the same time, has been applied to the converter. In this context, a pole placement design reduces the number of tuning parameters of LADRC to two to lessen the difficulty of parameter adjustment. The control scheme increases the tracking capability. A numerical example is provided to highlight the effectiveness of the control strategy. The tracking performance and step response are observed via several simulation studies using MATLAB/Simulink tool. It is demonstrated that the algorithm used in study is alternative way of tuning duty cycle of the boost converter instead of PID control technique. The performance of the controller is evaluated with a number of performance metrics. The tabulated results validate the controller's efficacy.
