Control allocation method was investigated with the background of aircraft with multiple control effectors. A new optimal control allocation method, bases sequence control allocation, was put forward. The optimal objectives were divided into control objective and mission objective, and the control objective should be fulfilled firstly. The actuators were recombined, and the efficiency vectors of the actuators were treated as the bases of multidimensional space. All of the bases were sequenced according to the control object and the mission objective. Then the optimization of redundancy system was transformed to a sequencing problem. Comparison with other allocation method and control system simulation results show the bases sequence method can achieve the objective accurately and optimally, and can be computed in real-time. The response of the control system is rapid and accurate, and shows good decouple performance among axes.
