GUIDANCE AND ROBUST GYROMOMENT ATTITUDE CONTROL OF AGILE FLEXIBLE REMOTE SENSING SPACECRAFT

Abstract Some problems on guidance and robust gyromoment motion control of agile spacecraft (SC) for remote sensing the Earth surface are considered. Elaborated methods for dynamic research of the SC programmed angular motion at principle modes under external, structural and parametric disturbances, partial discrete measurement of the state and digital control of the gyro moment cluster (GMC) by the minimum-excessive gyrodine scheme, are presented.
