Research On Track-guided Algorithm And In-orbit Control Of Space Vehicle

In recent years, with the development and use of space, many new concepts forspace vehicles have been raised, which has broaden the scope of new applicationsspace, raised many hot issues, such as orbital maneuvering vehicle problems, it alsoincludes the orbital maneuvering guidance algorithm research, trajectory planningand in-orbit control of space missions. This article intends to conduct in-depth studyof these hot issues.The aircraft mathematical modeling is the basis of the aircraft space mission.Firstly, this article has established the mathematical modeling of the objects whichare studied, the C-W mathematical model that meets the accurary requirements hasbeen obtained, this model is applicable to the assumption that the target star has anorbit eccentricity of0, and the relative distance of two stars is negligible with themain aircraft’s orbit radius, and therefore suitable for the study of small and mediumdistance from the orbital maneuvering. On the basis of the C-W model, this articlehas made in-depth analysis of in-plane and out-of-plane movement modal in form ofstate space, derived double pulses motor guidance algorithm in the light of theseconclusions above, which is the basis of the orbital maneuvering guidance algorithm.Vehicle guidance algorithm has been subject to attention. With growing energycrisis, as well as increasing number of space vehicles and space junk, energy savingand security are the two main themes in the field of space flight. To solve thisproblem, the article considered optimal energy consumption four-pulses orbit transferalgorithm for an arbitrary orbit transfer, the algorithm of this guidance is not limitedto the initial state and terminal state, only has restrictions on the initial orbit andterminal orbit, which has a high value onengineering applications.On the aspect of safety studying the article start from the field of view angleconstraint and anti-crash safety viewpoint, put forward new ideas for the use of slip-guided approach to solve the problem of the field of view angle constraint problem.The necessary numerical simulation of relationship of the guidance parameters andindicators are given, then gives the design of the spatial anti-collision and anti-plume-contaminated guided algorithm, and choose motorized time as simulationparameters to get the collection of the safe time and unsafe time, and finally select the intersection of two sets of safe time as final transfer time which meets therequirements.Finally, the article made research on the space configuration and controlproblem of the vehicle, firstly designed some special spatial configuration, thensimulated their characteristics, and then aimed at maintaining and reconstruction ofthe configuration, the article designed of optimal controller and predictive controllerfor these problems, and made analysis of the characteristics of the two control modesby changing the parameters.
