An online tracking-control strategy compositing disturbance-observer for hypersonic vehicles

A novel type of control scheme compositing an online tracking method and disturbance-observer is proposed for a hypersonic cruise vehicle with kinds of disturbances including flexible states, aerodynamic uncertainties, unmodeled dynamics and external disturbance. The online control method is provided on the basis of using aeropropulsive as well as elevator-to-lift couplings to design the controller without strategically neglecting or reducing the nonminimum-phase characteristic. Through an ingenious transformation, the control commands and reference trajectories are obtained simultaneously. The flexible dynamics on the pitch-rate tunnel is estimated by a state observer. A nonlinear disturbance observer is designed to estimate the disturbance and enhance the robustness of the composite scheme, then all kinds of disturbances are compensated or rejected effectively.
