Design, Analysis and Simulation of a Triaxial Spacecraft Attitude Control Testbed Based on Magnetic Bearing
Because of its technological significance, spacecraft attitude control testbed, have been widely used for the Earth-based testing of the spacecraft attitude systems. Traditionally, the spacecraft attitude control testbed is based on spherical air bearing, in this paper, a new kind of triaxial attitude control testbed (TACT) based on magnetic bearing is designed. The structure of the TACT is introduced, including it working principle. This paper especially described the hemispherical magnetic bearing applied in the TACT, designed a new kind of hemispherical magnetic bearing, and analyzed the distribution of the magnetic field in the bearing. In this paper, the magnetic force of the magnetic bearing is obtained by electromechanical-energy-conversion principles, the analytical equation of the mathematical model of the TACT is deduced, which make the feasibility of this design is verified.
