Optimal terminal guidance for exoatmospheric interception

open access: yesChinese Journal of Aeronautics, 2016
AbstractIn this study, two optimal terminal guidance (OTG) laws, one of which takes into account the final velocity vector constraint, are developed for exoatmospheric interception using optimal control theory. In exoatmospheric interception, because the proposed guidance laws give full consideration to the effect of gravity, they consume much less ...
