The invention discloses a multi-point imaging rapid maneuvering control method for a low-orbit optical remote sensing satellite, belongs to the technical field of aerospace, and aims to control the attitude of the satellite to an expected value in the shortest time under the condition that the reaction flywheel moment of the satellite and the angular momentum of the satellite are limited, so thatan optical load has an imaging state. The method comprises the following steps: carrying out kinematics and dynamics modeling on a low-orbit optical remote sensing satellite; carrying out satellite attitude planning; converting the attitude planning result from an orbit coordinate system to an inertial coordinate system; establishing a satellite error kinematics kinetic equation in combination with attitude planning information; dividing the attitude of the satellite into an inner loop and an outer loop, establishing a controller, and realizing multi-point imaging rapid maneuvering control ofthe low-orbit optical remote sensing satellite. The method has both attitude maneuver rapidity and high-precision attitude stability, in the attitude maneuver process, the satellite attitude can stably converge to the planned attitude, and the control method is simple in structure, easy to implement and capable of being applied to engineering practice.
