Abstract: Basedonthebacksteppingtechnique,amethodwasproposedfordevelopinganattitudepointingadaptivecontrollerofintersatellitelaserpowerbeaming.ThemodifiedRodriguesparameterwasusedtodescribethesatelliteattitude,andtheexpectedattitudewascalculatedbytheattitudematrixtransformation.Consideringtheuncertaintiesinmomentofinertia,thelimitedinputsandexternaldisturbances,anadaptivecontrollawwasestablishedbasedontheattitudekinematicsequations.Finally,thesystemwasprovedsteadybytheLyapunov′sstabilitytheory.Thesimulationresultsshowthattheerrorsofattitudeandangularvelocityreachzeroin15 s.Boththeangularvelocityandthecontrollingmomentarekeptundercontrol.Therefore,theinitialattitudeoftheusersatellitecanbecontrolledtotheexpectedonebyusingthecontroller,andboththeangularvelocityandthecontrollingmomentcanbekeptundercontroliftheparameterisfitting.Thatprovesthecontrolleriseffectiveandfeasible.
