Non-Linear Adaptive Control on Reusable Launch Vehicle Due to Actuator Stuck

Mohammed Junaid R, Laila Beebi M

Abstract: In this paper a nonlinear Lyapunov based controller is designed to compensate for the actuator stuck in Reusable Launch Vehicle during its descent phase. During re-entry phase, atmospheric contact forces become comparable with the gravitational forces. Inorder to cope up with the non linearities and uncertainties of the system, the control strategy based on adaptive state feedback and backstepping control is employed. Simulation results shows that the proposed controller works satisfactorily
