Abstract:

The design of efficient attitude control systems for extra-atmospheric vehicles is of considerable importance. The research discussed in this paper is directed to the problem of re-orienting a spinning vehicle in minimum time. The controllers are assumed to be thrust limited reaction jets or small rockets. The primary objectives of this research can be summarized as follows 1 To obtain efficient mathematical techniques for computing the time optimal control law for a wide class of vehicles in which small changes in attitude are required, and 2 to demonstrate the influence of spin rate, vehicle geometry, control magnitude and thruster configuration on the time required to optimally re-orient a spinning vehicle.
