The invention relates to a double-axis solar panel driving control method, which comprises the following steps of: calculating an
orbit illumination condition, namely an included angle beta between an
orbit system sun vector So and an
orbit surface, through an attitude and orbit
control system according to a time module and an
orbit determination module; according to the feedback SADA rotation angle and the solar vector of the
system measured by the
satellite platform, calculating the included angle between the normal of the sailboard and the solar vector of the
system in real time; different
control mode states of the sailboard driving mechanism are determined according to the solar vector of the orbital system and the included angle beta of the
orbital plane; and performing control
instruction distribution on each axis of the double-axis SADA according to each refined
control mode. According to the method, on the basis of ensuring on-
satellite energy when the SADA controls the sailboard to face the sun, vibration
coupling caused by double-shaft rotation in an existing design can be reduced as much as possible, and
satellite attitude stability is ensured; secondly, the load working loss time and the working
attitude stability are reduced, and the effective
working life of the satellite is guaranteed; in addition, on-satellite
shunting pressure and heat dissipation pressure can be reduced.
