- Abstract:
-
Hypersonic vehicles have ultrawide flight envelopes, a high flight Mach number, and complex flight environments. Due to these issues, this paper presented a control method based on fuzzy adaptive and designed altitude and velocity controllers. For the controllers, the effects of aerodynamic disturbance torque, measurement noise, interference with the steering gear, pneumatic parameter uncertainty, and aircraft model parameter uncertainty were analyzed in light of the aircraft height and speed control. The comprehensive effect of the above issues was then analyzed. Simulation results show that the altitude and velocity controllers have great tracking ability and robustness to various disturbances and uncertainties, and the designed controllers displays satisfactory results.
