The rigid body motion of CubeSat is strongly coupled with the elastic vibration of the flexible structure during the large angle attitude maneuver of the CubeSat. The drastic change of attitude will aggravate the jitter of the solar panel, which will then disrupt its stability. To deal with the contradictions between the rapidity and high-precision stability of large angle attitude maneuver of CubeSats and ensure the higher attitude pointing accuracy of the satellite after the attitude maneuver, this paper presents a multi-objective optimization algorithm based on the quintic polynomial path. This optimization algorithm can reduce the angular velocity as much as possible and obtain the optimal solution of maneuvering time. Then, a terminal sliding mode finite-time controller developed from a nonlinear disturbance observer is proposed. The nonlinear disturbance observer can calculate the disturbance, and the terminal sliding mode finite-time controller can perform feedforward compensation to improve the anti-interference ability of the control system, to achieve the desired finite-time attitude tracking control. Finally, a digital simulation platform based on the momentum wheel and magnetic torque is built. Experimental results show that the quintic polynomial path based on the multi-objective optimization algorithm can effectively reduce the angular velocity during attitude maneuver, and achieve the optimal time solution. The finite-time controller can effectively track the optimal path and ensure the rapidity and stability of attitude maneuvers.
