Abstract
In this paper, the methods for estimating uncertainties in the disturbance observer (DOB), a special kind of PID (SPID) and the active disturbance rejection control (ADRC) are discussed. The stability of ADRC is proven for a class of SISO nonlinear systems with unknown dynamics and disturbance. The comparison study and the analysis for ADRC show that under some conditions, DOB and SPID can be generalized for nonlinear systems with mixed internal and external uncertainties.
