In order to improve isolation degree of disturbance, a new ADRC based on NLE_PDFF feedback was proposed. Firstly, Mathematical model for precision analysis was formulated to evaluate the performance of the presented approach. And then, the NLE_PDFF_ADRC controller was designed. Finally, An experiment was performed to test the disturbance rejection of the NLE_PDFF_ADRC controller when the speed disturbance was from 3 to 5 Hz as compared with the traditional square PI compensation method. The results show that NLE_PDFF_ADRC can reduce the disturbance error 30%. The algorithm has been successfully applied to a stabilized platform.
