摘要

In this study, adaptive control of a two-axis gimbal system with actuator dynamics in the presence of parametric uncertainties is addressed. The considered gimbal system is a pointing antenna which can rotate over y and z axes and covers all line of sights. Adaptive dynamic surface control technique is used to overcome the `explosion of complexity' problem which appears in adaptive backstepping control design. By using the Lyapunov stability analysis, the convergence of the tracking error to origin and boundedness of all closed-loop signals are guaranteed. Finally, excellent performance of the proposed method for tracking the desired trajectories and also the effectiveness of this technique for controlling a two-axis pointing antenna are shown for a real antenna model in ADAMS.
