Sequencealgorithms of descent and prelanding maneuvers control in a hypersonic spacecraft
Abstract
The paper presents sequence algorithms for control of a hypersonic spacecraft (HS) which rely on a combination of the reference trajectory and terminal point forecast. The algorithms are implemented in an onboard computer. The procedure for sequencecontrol algorithms is development by optimizing linear and nonlinear laws. Comprehensive simulation of controlled HS motion included the following stages: analysis of programmed HS motion in descent and prelanding maneuvering; design of basic stabilization algorithms with due regard to disturbances over the autonomously controlled trajectory and for simultaneous control at the terminal trajectory; design of a sequencealgorithm for HS motion control; analysis of controlled HS motion subjected to a set of disturbances; and comparative analysis of systems which rely on sequence algorithms and conventional algorithms.
