This paper develops a novel fractional order model for a flexible two-mass system and proposes a fractional order controller to suppress residual vibration of this system. Based on fractional order constitutive law of viscoelastic material, a generic fractional order dynamic model has been derived for a flexible two-mass system, ranging from the pure elastic solids to the pure viscous materials. To suppress the residual vibration, a fractional order PD λ controller is proposed. Simulation results show that the proposed fractional order controller is effective and robust in achieving control requirements.
