An active disturbance rejection control method and system (1000) based on an error compensation expansion state observer. The method comprises: a linear active disturbance rejection controller obtaining an input signal and each output state of an expansion state observer, and outputting a first control signal; constructing an expansion state observer state space model for output displacement, converting a controlled object into an integrator series type, and based on the controlled object, obtaining an output displacement signal; inputting the output displacement signal and a control input signal into the expansion state observer, and obtaining each output state; and feeding back into the linear active disturbance rejection controller and the state space model. L'invention concerne un procédé et un système (1000) de commande par rejet actif de perturbation reposant sur un observateur d'état étendu à compensation d'erreur. Le procédé comprend les étapes suivantes : un dispositif de commande linéaire par rejet
