“…The heuristic algorithm is performed offline and with any kind of disturbance input. In other words, the way of selecting the disturbance in (1) does not affect the disturbance observer (29). The overall procedure of calculating disturbance observerbased controller gain matrices is shown in Fig.…”

“…However, the developed PI controller does not provide good performance, especially for the case high perturbed stand-alone power system. In [29] and [30], the external disturbance is estimated by an extended state observer (ESO) and a disturbance-observer, respectively. Then, a state feedback controller is designed.…”

“…12,13 Active Disturbance Rejection Control (ADRC) has been used to reject and compensate both internal dynamics and external disturbances, resulting in a robust controller. 14,15 ADRC does not need comprehensive information about the model of the physical systems; it uses Extended State Observer (ESO) to estimate the internal dynamics and external disturbances and then commands the system to reject and compensate these disturbances. Optimization of the ADRC is simple because it has only two parameters for tuning, the observer bandwidth (ωo) and feedback controller bandwidth (ωc).…”
