The summary of report：
This report 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, 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 plants. To suppress vibration, a fractional-order PD controller is proposed. Simulation results show that the proposed fractional-order controller is effective and robust in achieving control requirements.
