Vibration Suppression Control for Two-Inertia System using Reference Governor

This paper proposes a vibration suppression control for two-inertia systems based on a reference governor (RG), which is an add-on control scheme in closed-loop systems to supervise reference signals and enforce constraints. RGs have not previously been used for vibration suppression. An input shaping method has been used to suppress residual vibrations in flexible systems; however, although it modifies the reference signal like an RG does, it is not designed to enforce constraints. Simulation and experimental results show that the RG framework can suppress vibration in a two-inertia motor bench system.
