This paper highlights a robust contrller for DC servo motor. The controllers is proposed to control the DC motor actuator as a power source, the robust controller is designed  using an active disturbance rejection controller (ADRC) based on extended state observer (ESO). This  controller can accurately estimate the disturbance of the DC motor actuator is achieved. So controller make the DC motor actuator movement for tracking  a reference one in the presence of the modeling uncertainty and  the external disturbances during its process. The simulation and experimental results show that the proposed controller ensures good robustness and adaptability under modeling uncertainty and external disturbance.
