Abstract: Considering the special characteristics (long-cable structure) of the new design project with the integration of mechanical, electronic and optic technologies for the next generation large radio telescope, a corresponding control strategy and methodology are described. The strategy is that the problem of tracing a high nonlinear 3D curve is transformed into a problem of tracing a group of discrete points. Since the trajectory is repeatable for the same radio source, the self-regulate control method with a learning function is utilized. The numerical result has shown the feasibility and efficiency of the method. -
