چکیده
Adouble-gimbalcontrol-momentgyro (CMG) ismodeled usingLagrange’s equations,and an adaptive feedback control law is developed to follow a commandedCMG motion. The control law does not require knowledge of the mass properties of the CMG. A Lyapunovargument is used to prove that command following is achieved globally with asymptoticconvergence. Numerical simulationsare performed to illustrate the commandfollowingalgorithm. A CMG testbed was designed and constructed to implement and demonstrate the adaptive algorithm.This testbed is described, and experimental results are given.

متن کاملSpacecraft Angular Velocity Stabilization Using A Single-Gimbal Variable Speed Control Moment Gyro
Feedback controllers for the stabilization of the angular velocity vector of a rigid spacecraft using a single-gimbal Variable Speed Control Moment Gyro (VSCMG) are presented. Linearization of the equations of motion show that complete attitude stabilization is not possible via linear methods. Nonetheless, it is shown that the linearized angular velocity equations are controllable, and a simple...
