Shuttle ascent guidance and control
WebJun 10, 2015 · The proposed ascent optimal guidance method can successively generate online open-loop suboptimal controls without the design procedure of an inner-loop feedback controller. Considering model parameters' uncertainties and external disturbance, a sampling theorem is proposed that indicates the effect of the Lipschitz constant of the … Webplane changes in space as well as for the exoatmospheric portion of ascent of large multistage rocket vehicles. Guidance equations specifically for this latter applicatior are presented in Reference 1. When used for guidance equations, the linear-tangent steering has the advantage of not requiring
