| Outline of Final Research Achievements |
A reaction wheel system has been one of the effective method for a satellite attitude control. However, the attitude control system generally becomes huge and heavy. Novel attitude control system using a spherical rotor is proposed for an artificial satellite. Although the system has ability to miniaturize an attitude control system, a driving mechanism for a spherical rotor tends to be huge due to difficulty of three dimensional rotation. In proposed system, small DC motors are used to drive a spherical rotor to realize a small and lightweight attitude control system. We conduct experiments on attitude control of a satellite model with a spherical rotor by applying two-degree-of-freedom controller.
