Abstract :
On validating the feasibility of the antenna program, automatic or extreme tracking on the condition of multibody dynamics, in order to overcome mutual disturbance caused by antenna driving, an adaptive variable structure control is adopted and solves the model uncertainty of feed-forward compensation in antenna pointing control effectively. This adaptive variable structure attitude control scheme reduces the attitude change caused by modeling error, and has capacity of attitude control with usual feed-forward compensation as well. The paper presents adaptive variable structure control system design method for large-scale satellite antenna and full physical simulation results.
