Abstract
Using Lyapunov stability theory, an adaptive backstepping controller is presented in this paper for optimal descent tracking. Unlike the traditional approach, the proposed control law can cope with input saturation and failure which enables the embedded autonomy of lander system. In addition, this control law can also restrain the unknown bounded terms (i.e., disturbance). To show the controllerʼs performance in the presence of input saturation, input failure and bounded external disturbance, simulation was carried out under a lunar landing scenario.
