Trajectory planning for stabilization system of nanosatellite

Abstract

The paper deals with new trajectory planning and control method of high resolution multi-degree-of-freedom piezoelectric transducer used for nanosatellites stabtlization. The nanosatellite stabilization piezoelectric actuator was created using a contact point control algorithm ofpiezoelectric cylinder in the plane, perpendicuiar to satellite rotation axis. Control of the passive mass' trajectories leads to the increased resolution of the system which enables to orient the payload in a precise direction ofnanosatellite. System control by trajectory planning method was verified with numerical experiment, and partly tested in a laboratory with real system prototype.
