CONTROL METHOD OF KINETIC MOMENTUM OF SPACE VEHICLE DURING ORBIT CORRECTION

摘要

FIELD: mechanics; cosmonautics.;SUBSTANCE: invention refers to control of orientation and center-of-mass motion of space vehicle (SV). Method involves determination of the required SV orbit correction rate and maintenance of the specified SV orientation by means of powered gyros. During correction there determined is current vector of SV kinetic momentum and its variation is predicted. There chosen are groups of orientation engines for performing orbit correction and unloading of gyros till vector gets into the specified range of its values S_K⊂S, where S - range of available values . At that, for each group Σ'(i) i-x of engines, which provides the required correction rate - besides engines for gyro unloading - there predicted are values of total vector at the end of correction, which belong to S area. According to these values and target points to S_K area there determined are mismatches of vector and the possibility of eliminating them by control magnetic moments of SV current loops. If these mismatches can be eliminated, then the necessary loops are used, and among the groups Σ'(i) there chosen is the one that provides minimum working medium flow. Otherwise some parts of mismatches are eliminated by means of magnetic SV orientation system, and the other parts thereof - by means of orientation engines performing together with SV orbit correction the unloading of powered gyros.;EFFECT: reducing consumption of working medium of orientation engines.;1 dwg, 1 tbl
