Abstract :
Active disturbance rejection control (ADRC) is a heuristic but highly effective approach to controller-observer design. The advantages of the approach have been demonstrated in many applications but there is little available on its stability analysis. This paper shows that the nonlinear function used in ADRC results in stable behavior. Two examples are provided to demonstrate the robust stability and excellent performance of ADRC.
