Summary:The invention provides an aircraft overload control method adopting an integral observer. The method is applied to the field of aircraft overload control. Firstly, an attack angle sensor is adopted to measure the attack angle of the aircraft, and then an accelerometer is adopted to measure the longitudinal overload of the aircraft. Secondly, obtaining a damping signal through an attack angle by nonlinear differential transformation; thirdly, an integral observer is constructed according to the overload signal, the attack angle signal and the damping signal, comprehensive interference and uncertain signals of the aircraft pitching channel are observed, and the interference observed quantity is obtained; secondly, performing nonlinear integration on an error signal obtained by comparing the overload signal with the overload instruction to obtain a nonlinear integration signal; and finally, integrating the four types of signals to obtain a comprehensive overload control comprehensive signal, and transmitting the
