The invention provides a flywheel-participated satellite thruster under-actuated damping control method, which comprises the following steps of: firstly, acquiring a rotating triaxial angular velocity of a current satellite by using a high-precision gyroscope, and obtaining an initial bias rotating speed of a flywheel Y through an algorithm; biasing the flywheel Y at a fixed rotating speed to ensure that the angular velocities of the X axis and the Y axis of the satellite do not transfer to the Z axis; satellite under-actuated damping control is carried out by adopting an orthogonal thruster which only has thrust in two directions, and the condition that the whole satellite momentum moment is lower than a set value is taken as a control termination condition, so that the satellite attitude is rapidly stabilized after satellite and rocket separation.
本发明提供一种飞轮参与下的卫星推力器欠驱动阻尼控制方法,包括:首先使用高精度陀螺获取当前卫星的旋转三轴角速度,通过算法,得到飞轮Y的初始偏置转速;把飞轮Y偏置一个固定的转速,确保卫星的X轴和Y轴的角速度不向Z轴转移;采用正交且只有两个方向推力的推力器进行卫星欠驱动阻尼控制,以整星动量矩低于设定值为控制终止条件,实现星箭分离后卫星姿态的快速稳定。
