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.
Aiming at the problem that the dynamic inverse method is a kind of advanced aircraft control method which is difficult to ensure the robustness of the algorithm due to the precise mathematical model of the controlled object, based on the in-depth study of the aircraft uncertainty model, the dynamic inverse method is taken as robust control Of the inner loop, the outer loop robust control compensation for the model uncertainty is carried out.On the basis of the traditional H∞control, a comprehensive analysis and design of μ and a worst case analysis are carried out.From the simulation results, it can be seen that this The method not only ensures the robustness of the dynamic inverse method, but also improves the overall control performance.
