Abstract
This study presents control design based on Active Disturbance Rejection Control (ADRC) methodology to supress the effect of wing-rock motion in delta-wing aircraft. Two structures of ADRC have been addressed for the purpose of wing-rock motion rejection; one is based on Linear ADRC, and the other is based on Nonlinear ADRC. The setting of design parameters of designed ADRC controller is another problem, which has been solved by using modern optimization technique. This work has suggested Butterfly Optimization Algorithm (BOA) for tuning these design parameters in such a way an optimal performance of controller could be reached. A comparison study in performance between LADRC and NADRC has been conducted via numerical simulation show the superior of LADRC over the NADRC in terms of rejection capabilities. Moreover, the simulated results showed that the BOA could successfully improve the performance of proposed controller as compared to try-and-error procedure.
