Active disturbance rejection control: methodology and theoretical analysis. (2014, methodology): “Since b bð Þ and b að Þ are the estimations for the unknown functions bð Þ and að Þ, it is easy to find out that, to achieve controlling of y, the “total disturbance” to be handled is xnþ19bðx; z;wÞþaðx; z;wÞu b bðbxÞ b aðbxÞu: Moreover, the output b s of the EHGO (17) is to estimate this total dist”

On convergence of nonlinear active disturbance rejection for SISO systems (2012, neutral): “Apart from some early preliminary arguments in [2] for reference tracking of linear systems, and some efforts on state observer in [14] for linear ADRC, and linear ADRC [1] also, there is still no, up to date, a rigorous convergence proof for nonlinear ADRC.”
