Antenna pointing apparatus mounted on satellite using feed forward with reference model

摘要

An optical antenna pointing controller for an optical antenna system having an optical antenna and biaxial gimbal mechanism coupled to the optical antenna and mounted on the satellite is provided. Feedback control in the controller is gain-stabilized by a nominal compensator, and disturbance is suppressed by a robust compensator, further, a target satellite is captured quickly with the aid of a reference model and feedforward, thus providing quick response without dependency on the band width of feedback control system.
