Paper Abstract

This paper presents the development of an ultra precision optical satellite relative-trajectory simulator. It is commonly known that by combining two prisms of equal apex angle in near contact and by independently rotating them about an axis parallel to the normals of their adjacent faces, a ray can be steered in any direction within a limited cone. Due to the request of high precision, we use the table-looking method rather than the conventional approximately formula to transform the angle between the azimuth and elevation angle of the relative-trajectory and the angle of the servo-motor. To achieve a stable and accurate control of the system, a Proportional-Integral-derivative (PID) controller is used and the controller was optimized use the Genetic Algorithm. Furthermore, we simulated the system with Matlab program under different bandwidth. The results demonstrate that the proposed position control system achieves a good control performance. The simulation indicates that PID controller performed well on the satellite relative-trajectory simulation.
