Abstract

© 2022 IEEE.In this study, a new three-dimensional (3D) guidance law based on an the augmented proportional navigation guidance law utilizing a disturbance observer (DOB) technique is proposed considering different target models. The Augmented Propartional Navigation (APN) guidance law is designed by considering the acceleration information of the target. For this purpose, a nonlinear disturbance observer is used to obtain the target acceleration. In numerical simulation studies, the performance of the classical APN guidance law and the new design of the APN guidance law against two different targets with non-maneuvering and maneuvering motion were investigated. Finally, when the design of the APN guidance law, it can be designed without the need for target acceleration information. Moreover, when the results obtained are examined, it can be seen that this newly presented design is more successful than the classical APN guidance law.
