| 英文摘要 |
| Based on the polynomial sum of squares (SOS) techniques, a nonlinear local stabilization control approach is designed for the problem of flexible satellite attitude maneuver and Based on the polynomial sum of squares (SOS) techniques, a nonlinear local stabilization control approach is proposed
for the problem of flexible satellite attitude maneuver and vibration suppression. According to the structural features of attitude system,
a nonlinear local stabilization controller is developed and the complexity of attitude control design is reduced effectively by employing
a separation principle for the reduced-order observer and state feedback. On this basis, the corresponding conditions of nonlinear local
stabilization, which can be checked through convex optimization algorithms, are presented by using the SOS and S-procedure theory,
and the analytical solution of nonlinear attitude controller can be constructed if the optimization problem is solvable. Finally, this method
is applied to the attitude control of a flexible satellite and the simulation results show that both the fast large angle attitude maneuver
and the vibration suppression are well realized. |
