To　satisfy　the　requirements　for　small　satellites　that　seek　agile　slewing　with　peak　power,　this　paper　investigates　integrated　power　and　attitude　control　using　variable-speed　control　moment　gyros　(VSCMGs)　that　consider　the　mass　and　inertia　of　gimbals　and　wheels.　The　paper　also　details　the　process　for　developing　the　controller　by　considering　various　environments　in　which　the　controller　may　be　implemented.　A　fuzzy　adaptive　disturbance　observer　(FADO)　is　proposed　to　estimate　and　compensate　for　the　effects　of　equivalent　disturbances.　The　algorithms　can　simultaneously　track　attitude　and　power.　The　simulation　results　illustrate　the　effectiveness　of　the　control　approach,　which　exhibits　an　improvement　of　80　percent　compared　with　alternate　approaches　that　do　not　employ　a　FADO.
