![METHODS AND SYSTEMS FOR IMPOSING A MOMENTUM BOUNDARY WHILE REORIENTING AN AGILE VEHICLE WITH CONTROL MOMENT GYROSCOPES](/abs-image/US/2011/05/05/US20110101167A1/abs.jpg.150x150.jpg)
Abstract:
Methods and systems are provided for reorienting an agile vehicle, such as a satellite or spacecraft, using a control moment gyroscope (CMG) array. The CMG array comprises a plurality of CMGs onboard the agile vehicle. A method comprises obtaining an input torque command for reorienting the vehicle using the CMG array and, when the angular momentum of the CMG array violates or is approaching a momentum boundary criterion, decreasing the input torque command in the kinetic momentum direction, resulting in a modified torque command, and operating the CMG array using the modified torque command.
