Abstract
In this paper, the system functions(S-Function) such as Tracking-Differentiator (TD), Extended-State-Observer (ESO) and Non-linear-State-Error-feedback (NLSEF) were written, the model of Auto Disturbance Rejection Controller (ADRC) was established. Through a simple second-order system as the object, the ADRC and PID algorithms were simulated. After analysis and comparison of these two different control algorithm simulation results, the results show that ADRC has good dynamic performance and strong robustness.
