The invention relates to an optical remote sensing satellite attitude planning and imaging control method based on a reference model. The method comprises the following steps: establishing an attitude coordinate system and dynamics; performing agile attitude planning based on the reference model; setting attitude planning constraint parameters; converting the attitude planning result from an orbital coordinate system to an inertial coordinate system; establishing a satellite error kinematics and dynamics equation in combination with attitude planning information; modeling control moment nonlinearity and space environment interference; the invention discloses an adaptive attitude controller. According to the invention, agile imaging attitude control in different satellite imaging modes can be realized, the imaging function of a satellite system is enhanced, and the remote sensing image acquisition range of a satellite is widened. Meanwhile, the influence of control moment nonlinearity and space environment interference on attitude control precision is suppressed, and it is ensured that the satellite attitude maneuver process is rapid and the attitude is stable and accurate after convergence. The control method is easy in parameter debugging, high in robustness and suitable for control system design of small and medium-sized low-cost optical remote sensing satellites in engineering practice.
