An Extended State Observer Based on Tracking Differentiator

Zhu Jianhong, Zhaojing Zhang, Yang Huizhong

Abstract

A series tracking differentiator (TD) that is in the form of observer is used as substitute for the extended state observer (ESO) in active disturbance rejection controller (ADRC). This improved ESO independently of original system model is not only simple for the parameters tuning, but also good for filter performance. The simulation results show that the method is exceptional.
