Description
Summary:A robust control method for super-maneuver flight based on the adaptive observer has been designed in this paper to solve the uncertainty of aerodynamic parameter, external disturbance and model error. The discontinuous projection adaptive law is adopted in the fast and slow loops to online estimate the uncertainty of aerodynamic parameter. The external disturbance and model error are observed and compensated by the adaptive observer which designed by applying the adaptive law in the general observer, and then Lyapunov function is selected to analyze the stability of whole system to obtain final control signal. The digital simulation of super-maneuver flight proves that the controller can effectively resist interference caused by the uncertainty of aerodynamic parameter, external disturbance and model error, and enhance the robustness of the system.
