One nearspace hypersonic aircraft dynamic surface adative backstepping control design based on nonlinear neumatic/ thrust vectoring composite control

One nearspace hypersonic aircraft model based on pneumatic/ thrust vectoring composite control was built, compound controller optimization scheme was adopted to cooperate pneumatic/thrust vectoring compound controller equivalent dynamic characteristic to reference model during dynamic assign. In the course of adaptive backstepping design, the dissertation employes the dynamic surface control strategy to eliminate the explosion of terms by introducing a series of first order filters to obtain the differentiation of the virtual control inputs. Lyapunov stability theorem guarantees the error uniformly bound. Both theory analysis and 6 DOf simulation verification show the simpleness and arithmetic availability.
