基于路径规划和反推技术挠性航天器姿态控制
Attitude control of flexible spacecraft based on path planning and backstepping technique
摘要
Abstract
In order to suppress appendages' vibration of a flexible spacecraft during attitude maneuver, an adaptive attitude control scheme was proposed based on path planning and backstepping technique. The maneuver path was planned to solve the conflict between swiftness and overshoot in traditional control as well as to suppress the vibration of flexible appendages. For flexible spacecraft dynamics and kinematics constituting a nonlinear cascaded system with uncertainties, an adaptive attitude controller was designed based on backstepping technique, in which only the output information was utilized. And the global uniform ultimate bounded stability of the system has been proved. For the system subject to inertia parameter uncertainties and bounded disturbances, the proposed controller in this paper can not only suppress the flexible appendages' vibration, but also realize fast maneuver and fast stability of spacecraft attitude. Simulation results show the effectiveness of the proposed adaptive controller.关键词
