摘　　要：针对动态逆方法作为一种先进飞行器控制方法因需被控对象精确的数学模型而难以保证算法鲁棒性的问题,在深入研究飞行器的不确定性模型基础上,将动态逆方法作为鲁棒控制的内环,对模型不确定性进行外环鲁棒控制补偿.在传统H∞控制基础上进行了μ综合的分析与设计,并进行了最差情况分析.从仿真结果可以看出,这种方法既保证了动态逆方法的鲁棒性,又提高了整体控制性能.For the problem that dynamic inversion control as an advanced control method of aircraft needs for precise mathematical model, so its robustness is difficult to be ensured. Therefore, the uncertainty model of aircraft is introduced deeply. The dynamic inversion method is used as inner loop of robust control, and robust control is to compensate for model uncertainty as outer loop. By the analysis and design of μ based on traditional H∞, the worst-case analysis is given. The simulation results show that the method can improve the robustness and the performance of the aircraft.
