Abstrakt: Considering overactuated satellite optimal control allocation problem with redundant reaction wheels, in order to achieve minimum total energy consumption and torque allocation deviation as a goal, an energy/torque dynamic control allocation algorithm is proposed by defining relevant optimized objective function. Also, the proposed method takes nonlinear dynamics into account and modifies the initial control allocation result. Finally, mathematical simulations are used to verify the performance of the algorithm, the result shows its feasibility and effectiveness. [ABSTRACT FROM AUTHOR]
