A problem in optimal reorientation of asymmetric space vehicles

The problem of large-angle, three-dimensional reorientation of asymmetric space vehicles in a fuel optimal manner is considered. A general problem is posed and solved numerically. The resultant numerical data is compared to a feedback configuration derived from a subset of the general problem. In both instances, Pontryagin's Minimum Principle is utilized to determine the set of differential equations which describe the optimal trajectory. The control is presumed to be unconstrained, resulting in a continuous optimal control.
