System Identification-Based Dynamics Control for X-Y Pedestal Satellite Antenna

Abstract

Subspace method-based system identification and six different transfer functions as product of this method have been developed and embedded in the motion control unit of the X-Y pedestal satellite antenna. Fit estimation data of these six transfer functions is changing from 95.46% to 99.99% with a RMSE (root mean square error) degree from 0.00502 to 0.00984, whereas the target RMSE degree value is 0.05.
