摘要
The method involves using proportional-differential control with gains varying according to the local geomagnetic field, whose instantaneous values in two directions (x,z) are measured (1) with conventional magnetometers. From knowledge of the satellite's dynamic characteristics (6), and given the constraints on damping coefficients and angular frequencies in the characteristic polynomial, instantaneous values of gains (row matrices of the control law) are found. Roll-yaw angles and rates are measured (3) to obtain a desired value of torque. A magnetic moment is determined (4) which by interaction (5) with the geomagnetic field generates a real torque enabling the system loop to be closed.
