Abstract:Design and adjusting rule of auto-disturbance-rejection controller are proposed for a class of first order nonlinear plants. Tracking differentiator and nonlinear combination are simplified. According to the analysis of observing error of a secould order extended state observer, an empirical tuning rule is proposed based on theoretic deduction and simulations. Simulations on a multivariable plant with adjustable zeros demonstrate validity of the tuning rule.
Keywords:Nonlinear plants  auto-disturbance-rejection controller  tuning rule  multivariable plant with adjustable zeros
