Outline of Final Research Achievements

This research has focused on 1) underactuated attitude control of satellites under input directional constraints and 2) optimal fault-tolerant configurations of actuators. Underactuated control is a possible solution to enhance fault-tolerance of satellites, which enables driving a satellite state with less number of inputs than the number of state. This research has proposed magnetic attitude control method for a spinning satellite that uses only a magnetometer data for the feedback control. Furthermore, optimal fault-tolerant configurations of control moment gyros and thrusters have been derived. The optimal configurations of the actuators maximize the controllability of satellites considering underactuated control. The effectiveness of these proposed methods are numerically verified.
