This paper is about applying Active Disturbance Rejection Control to UAV flight control system. The principle of ADRC is introduced. Tracking differentiator is used at the transition phase so that the given signal can be followed up quickly and accurately. The system uncertainty is evaluated by Extended State Observer real-timely and then is used as an input of the control in the form of feedback. Thus, the state is well controlled by the real-time compensation of system disturbance. Simulation results show that this technology has the following benefits: high disturbance immunity, high control quality, high accuracy and simple algorithm.
