Active Disturbance Rejection Control for Discrete Systems with Zero Dynamics
International Journal of Robust and Nonlinear Control
In this paper, a discrete active disturbance rejection control (DADRC) scheme is proposed to manipulate linear input-output systems with zero dynamics. The DADRC is formulated according to the relative degree of the system output and is designed to track a reference and cancel both internal uncertainties and external disturbances. A parameter tuning method is also presented based on a part of the model information. The robustness and effectiveness of the designed scheme are demonstrated via numerical simulations.
