| چکیده | ||
| This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of the proposed control strategy is a new combination of the attitude control methods including backstepping, dynamic inversion, and adaptive control methods which will be called Backstepping-Dynamic inversion-Adaptive (B.D.A) method. In the proposed method, a single control variable is considered as the bank angle while the angle of the attack and the side slip angle will be stabilized in their inherent value. The purpose of this control is the attitude control of the vehicle to track the commanded bank angle and keep the vehicle in the desired trajectory. Lyapunov stability analysis of the closed-loop system will be performed to guaranty the stability of the vehicle in the presence of constraints. Performance of the controller will be evaluated based on six Degrees of Freedom (6-DOF) model of the re-entry capsule. Also, the results of the proposed control algorithm will be compared with the Backstepping Dynamic inversion (B.D) control method. | ||
