Abstract
A new anti-windup scheme, whose structure stems from the model-following control (MFC), is developed in this paper for the linear system with actuator saturation. Under the proposed framework, the effect of actuator saturation is eliminated when parameters are chosen properly. Stability analysis is also provided on the basis of two different approximations for the saturation nonlinearity. As for two representative systems from industrial process viz. FOPDT and SOPDT with actuator saturation, it shows that the proposed scheme is an effective alternative for anti-windup design. And besides, it demonstrates robustness on the parametric uncertainties of the above systems as well as performance of disturbance rejection.
