Time-Optimal Velocity Control of a Spinning Space Body

The problem of minimum-time angular velocity control of a spinning space body, with a sinigle axis of symmetry, is examined. The control thrusts are assumned bounded. Two-axis, gimballed, and single-axis controls are considered. The optimal controls law is derived for each method. Comparison of the...

Description
Summary:The problem of minimum-time angular velocity control of a spinning space body, with a sinigle axis of symmetry, is examined. The control thrusts are assumned bounded. Two-axis, gimballed, and single-axis controls are considered. The optimal controls law is derived for each method. Comparison of the response times indicates that gimballed control is best.
