Abstract:

A new control method based on prescribed performance is proposed for non-affine model during landing, while considering the impact of the airwake disturbance. In contrast to the traditional backstepping method that the carrier model should be transformed into an affine form by setting the hypothesis condition, the proposed method transforms the carrier-based model into a more general non-affine pure feedback form and relaxes the assumptions. The proposed control scheme is capable of guaranteeing tracking errors of height, velocity, altitude, pitch angle, and pitch rate with the prescribed performance. The presented controller possesses much lower computational costs, while has strong robustness for the airwake disturbance, and improves the accuracy of the landing tracking.
