摘要： 针对转子系统的非线性恢复力模型与非线性振动控制问题,采用变宽度与变形状的隶属度函数构成的模糊规则的模糊PID控制的电磁作用器,实现对转子系统的非线性恢复力的处理和非线性振动的完全控制。使用具有非线性恢复力的轴承和电磁作用器的Jeffcott模型,进行转子系统的非线性振动控制的仿真计算,并通过使用模糊PID与传统PID两种控制方法的仿真及比较,表明使用所提出的模糊PID控制器能对非线性恢复力进行自学习的模糊处理和实现转子系统的主谐波和分数谐波区域的完全振动控制,也强化了转子系统的适应能力。

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.

Key words: FUZZY-PID control, electromagnetic actuator, nonlinear rotor, vibration control, simulation
