Abstract

Abstract: In order to overcome the problems which are the model of the nonlinear restoring force and the nonlinear vibration control, the vibration control of the nonlinear rotor system and the processing the nonlinear restoring force were accomplished based on the electromagnetic actuator using the FUZZY-PID controller with the fitness function of the variable width and variable geometric shapes. Using the Jeffcott rotor model with the nonlinearities of the forces of the bearing and the electromagnetic actuator, the simulations of the vibration control on the rotor system were performed. Through comparing with the control methods of the traditional PID and the FUZZY-PID and their results, the simulation results show the proposed FUZZY-PID controller can process the model of the nonlinear restoring force by the self-study and the nonlinear vibration control in the vicinities of the major critical speed and sub-harmonic critical speed and the rotor system is improved with a stronger ability of the interference rejection.
