摘要

大角度姿态机动是航天器执行任务时常见的一种机动方式，如对星校准导航系统等。已有的姿态跟踪研究大多着眼于优化时间和燃料成本，而忽略了对姿态跟踪的平顺性要求和角速度限制。针对大角度姿态机动的平稳过渡问题，提出了一种非线性控制算法。在姿态反馈控制回路中加入非线性滤波器，实现大角度机动的角速度控制。仿真结果验证了该方法的有效性和可靠性。

Nonlinear control algorithm for smooth transition in large-angle attitude maneuver

Large-angle attitude maneuver is common during the mission of spacecrafts, such as aligning to star to calibrate navigation system. Published works on attitude tracking always focus on optimizing the time and fuel cost, neglecting the smoothness requirement and angular speed limitations. In this paper, a nonlinear control algorithm is prompted for smooth transition in large-angle attitude maneuver. A nonlinear filter is added to the attitude feedback control loop, to carry out angular speed control in large-angle maneuvers. Simulation results demonstrated the effectiveness and reliability of proposed approach.
