Summary: With regard to the interactions uncertainty on control efficiencies of the multiple effectors aircraft, a robust control allocation strategy is proposed based on the hybrid optimum theory. The nonlinear interactive efficiency is described as the structured uncertainty, the robust least-squares control allocation model is established based on the optimal object of minimum allocating worst-case, and an equal configuration using the linear matrix inequality is proved. Taking the restriction of deflection energy into consideration, the robust mixed-optimization control allocation model is established to avoid the saturation of the control surface. The simulation shows that, the proposed strategy can acquire concerted allocation solution with the interactions uncertainty tolerated, which has a preferable robustness.
