To remove the funitional payload variation, the attitude oscillation and trajectory tracking error of civil UAV in complex environment, a combined inner and outer control strategy for the civil UAV is designed based on the interval system control theory and dynamic tracking error minimization principle, which can guarantee the attitude stabilization in inner loop and the heading tracking in outer loop, thus solving the control effect deterioration and trajectory error drawback of the existing UAV with large scale model variation. The simulation results show that, the proposed combined control strategy can keep flight state's stabilization and effective trajectory tracking with good closed-loop robustness. This study is useful to develop effective and automatic civil UAV system's flight control strategy.
