One nearspace hypersonic aircraft nonlinear neumatic/thrust vectoring composite control design based on uncertain

One nearspace hypersonic aircraft model based on pneumatic/ thrust vectoring composite control was built, compound controler optimization scheme was adopted to cooperate pneumatic/thrust vectoring compound controler equivalent dynamic characteristic to reference model during dynamic assign. Due to the linear parameter uncertain term and unmodeled dynamic caused by high mach number and high temperature, the research object was expanded to a nonlinear dynamatics system of linear paramter uncertain in control maxtrix, the paper provided adaptive adjust function to compensate the influence from the uncertain, and designed the robust term to solve the problem from approach error. Project operator was adopted to design the final direct adaptive control law which avoided the possible singularities of the controller. In the course of adaptive backstepping design, this paper employed 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. The simulation result shows the arithmetic availability.
