摘　　要：A multi-objective parametric design method that based on the robust observer is proposed for the attitude control of satellites with super flexible netted antennas.First,a parametric observer-based controller is obtained based on the eigen-structure assignment theory.The closed-loop poles are assigned to desired positions or regions,and full degrees of freedom of the design,which are characterized by a set of parameters,are preserved under the proposed control law.Second,the obtained parameters are comprehensively optimized to make the closed-loop system have lower eigenvalue sensitivity,a smaller control gain,and stronger tolerance to high-order unmodeled dynamics and external disturbances.Finally,comparative simulations are carried out based on practical engineering parameters of a satellite in order to verify the effect of the proposed method,and also to show their superiority over the traditional proportional-integral-derivative(PID)controller with filters and the traditional dynamic compensators.
