description abstractThe classical massonmovingbelt model describing frictioninduced vibration is studied. The primary resonance of dryfriction oscillator with fractionalorder PID (FOPID) controller of velocity feedback is investigated by Krylov–Bogoliubov–Mitropolsky (KBM) asymptotic method, and the approximately analytical solution is obtained. The effects of the parameters in FOPID controller on dynamical properties are characterized by five equivalent parameters. Those equivalent parameters could distinctly illustrate the effects of the parameters in FOPID controller on the dynamical response. The effects of dry friction on the dynamical properties are characterized in the form of the equivalent linear damping and nonlinear damping. The amplitudefrequency equation for steadystate solution associated with the stability condition is also studied. A comparison of the analytical solution with the numerical results is fulfilled, and their satisfactory agreement verifies the correctness of the approximately analytical results. Finally, the effects of the coefficients and orders in FOPID controller on the amplitudefrequency curves are analyzed, and the control performances of FOPID and traditional integerorder proportionalintegralderivative (PID) controllers are compared. The comparison results show that FOPID controller is better than traditional integerorder PID controller for controlling the primary resonance of dryfriction oscillator, when the coefficients of the two controllers are the same. This presents theoretical basis for scholars and engineers to design similar fractionalorder controlled system.
