Low-energy planetoid precise track transfer detection method for complex constraints

Abstract

The invention discloses a low-energy planetoid precise track transfer detection method for complex constraints, and belongs to the technical field of aerospace. The method comprises the steps that firstly, various complex non-consistent strong coupling constraints needing to be met by a track detection design task are determined, and the mapping relation between track design parameters and the various complex non-consistent strong coupling constraints is built; under a mass center rotating coordinate system, a detector dynamics equation is built; an initial value is provided through the builtlinear detector dynamics equation, a precise quasi periodicity track under an ephemeris model is obtained by adopting a nonlinear dimension reduction method and second-order differential coercion; onthe basis of the precise quasi periodicity track under the ephemeris model, a quasi manifold disturbance method is adopted for optimizing the obtained transfer track initial value; for the various complex non-consistent strong coupling constraints, the obtained transfer track initial value is corrected, and the precise low-energy transfer track is obtained. The method has the advantages of being high in efficiency, good in convergence and low in energy needed by transfer.
