Abstract:
In this study, to resolve the uncertainties associated with aerodynamic parameters, external disturbances, and model error, we design a robust control method for super-maneuver flight based on an adaptive observer. To observe and compensate for external disturbances and model error, we design the adaptive disturbance observer to apply the adaptive rule of a general observer. We adopt this adaptive rule in both fast and slow circuits to estimate the uncertainty of the aerodynamic parameters, and then use the Lyapunov function to analyze the stability of the whole system and obtain the final control signal. Our digital address verification of the super-maneuver flight proves that the controller can effectively resist interference caused by the uncertainties associated with the aerodynamic parameters, external disturbances, and model error, and thereby enhances the system robustness.
