Sudden disturbance suppression control considering constraints for high-precision stage using Reference Governor

Reference Governor (RG) is a control method used in add-on control schemes in closed-loop systems to supervise reference signals and enforce constraints. Although previous studies of RG have mainly discussed a command tracking performance, a disturbance suppression performance has been rarely discussed. This paper proposes a novel control method based on RG to suppress the effect of sudden disturbance. Simulations and experiments are performed to demonstrate the effectiveness of the proposed method.
