Due to its multi-mission profiles, complicated flight conditions, and large Mach number, the flight control system of NHV (near-space hypersonic vehicle) might have strong nonlinearity, coupling and fast-variability and be impacted by strong external disturbance and internal uncertainty. It is a great challenge for control law design. Based on the configuration of NHV, the aerodynamic/engine integrated...
An optimal generalized predictive control (GPC) law is developed for a near-space hypersonic vehicle in reentry flight. The nonlinear disturbance observer (NDO) technique is combined with the control law for the output to track the reference attitude angles and angular velocities in the presence of uncertainties and disturbances. The prediction defined on finite horizon is carried out via Taylor series...
