  • Abstract
    This paper concerns with stability characteristics of active disturbance rejection control for nonlinear time-varying plants that are largely unknown. In particular, asymptotic stability is established where the plant dynamics is completely known. In the face of large dynamic uncertainties, estimation and tracking errors are shown to be bounded, with their bounds monotonously decreasing with their respective bandwidths.
