Abstract—

The possibility of stabilizing the gravitational orientation mode of a massive artificial Earth satellite (AES) by the torque produced by electromagnets interacting with Earth’s magnetic field is shown. As an example, the control of rotational motion of the satellite like Bion M-1 and Foton M-4 is considered. Control is accomplished by changing the currents in the electromagnets. The control law is considered, which provides damping of the disturbed motion of a satellite and its stabilization in the gravitational orientation mode. To form this law, it is sufficient to have the readings of a triaxial magnetometer and of an angular velocity sensor. The control law efficiency is verified by mathematically modeling satellite motion relative to the center of masses, under an effect of gravitational and aerodynamic torques, as well as the torque produced by electromagnets.

电磁控制系统稳定人造地球卫星（AES）的重力方向模式

摘要-

示出了通过电磁体与地球磁场相互作用产生的转矩来稳定大型人造地球卫星（AES）的重力定向模式的可能性。例如，控制像Bion M-1和Foton M-4这样的卫星的旋转运动被认为。通过改变电磁体中的电流来实现控制。考虑了控制律，该律提供了对卫星干扰运动的阻尼及其在重力定向模式下的稳定性。为了形成该定律，具有三轴磁力计和角速度传感器的读数就足够了。在重力和空气动力学转矩以及电磁体产生的转矩的作用下，通过对卫星相对于质心的运动进行数学建模，可以验证控制律的效率。
