Abstract :
This paper presents comments on active disturbance rejection control (ADRC) in four aspects as follows: (1) tracking differentiator; (2) nonlinear combination of proportional, integral, and differential errors; (3) extended state observer; and (4) disturbance rejection. Applications of ADRC are briefly introduced.
