摘要	To satisfy the needs of novel imaging modes for at-titude rapid maneuver and high precision tracking control, a control strategy combining feedforward and feedback control is proposed for flexible satellite with hybrid actuator (pyramid configuration control moment gyroscopes (CMG) and reaction fly-wheel). In the design of feedforward control, to fully consider the constraints, such as torque output capacity of CMG group, singularity and vibration suppression performance, a Legendre pseudospectral method which could plan the optimal satellite at-titude and frame angle rate of CMG group is presented. In the design of feedback control, with the torque capacity of flywheel, attitude rapid maneuver and energy constraints being the cost function, a tracking control algorithm based on nonlinear model predictive control (NMPC) is given to compensate the error of initial state and rotational inertia. The results show that, in the case of inertia error, the proposed control method is effective and shows a strong robustness. Copyright 2017 Acta Automatica Sinica. All rights reserved.
