[0088] Aiming at the attitude control problem of unmanned helicopter, the attitude dynamics model of unmanned helicopter is first analyzed. Then a nonlinear continuous robust control algorithm based on neural network feedforward compensation is designed, and stability analysis based on the Lyapunov method is carried out. It is proved that the designed controller can realize the semi-global progressive tracking control of the unmanned helicopter attitude. The experimental results of attitude control flight show that the present invention can enable the unmanned helicopter to achieve rapid and accurate stabilization control, and has good robustness to the uncertainty of the system.
[0089] The present invention proposes a novel attitude control method for a small unmanned helicopter based on neural network feedforward and nonlinear continuous robustness. This method has strong adaptability to the uncertainty of the system model and environmental interference, and can significantly...
