The invention discloses an auto disturbance rejection control method for a space robot with actuator saturation. The method comprises the following steps: arranging a proper transition process for anexpected track and posture of a system by designing a tracking differentiator, and meanwhile, acquiring a differential signal with an expected value to make preparation for subsequent controller design; and designing a sampling expansion state observer by utilizing a discrete output signal, performing real-time estimation on the total non-linear uncertain items which are formed by the state of thespace robot system as well as coupling and external disturbance, and compensating the estimation values of the non-linear uncertain items into an error feedback control rate. By the method, adverse influence on the system by non-linear factors such as internal and external disturbance can be avoided, and the fact that an actuation mechanism implements accurate position and posture control on thespace robot within the saturation range can be guaranteed. The control strategy provided by the invention has a good control effect on the space robot system considering sampling output and with actuator saturation, and can be widely applied to other non-linear systems.
