摘要

The problem of angular velocity stabilization for the spinning spacecraft is considered. The spacecraft is assumed to be supplied a passive inertial energy dissipater in the form of a spring-mass-dashpot and small resistojels. The satellite is subjected to a combination of an excitational time varying torque and a control torque. The energy-based speed-gradient (SG) control law is proposed and numerical examination of the closed-loop system is provided. Numerical simulations have shown the effectiveness of SG control strategy and robustness properties with respect to excitation torque amplitude.
