本文研究了压电陶瓷和电流变液驱动的混合智能复合材料梁的振动模糊控制问题。研究了粘贴压电陶瓷的电流变液对碳纤维增强塑料悬臂梁在正弦外激励下的振动特性。由于电流变液作动器的强烈非线性，难以将线性控制理论应用于振动控制，因此，形成了包含两个作动器的受控元件的模糊模型。模糊模型的参数辨识采用混合神经模糊系统。利用现代控制理论，在模糊模型的基础上，设计了复合材料梁振动抑制模糊控制器。通过仿真和实验验证了模糊控制器对振动控制系统的效果。
In the present study, the fuzzy control of vibration is investigated for a hybrid smart composite beam actuated by piezoceramics and electro-rheological fluids (ERFs) actuators. A carbon fiber reinforced plastics cantilevered beam containing ERF with bonded piezoceramics is vibrated under forced sinusoidal external excitation. A fuzzy model of the controlled element containing two actuators is formed because the application of a linear control theory to the vibration control is difficult due to intense nonlinearity in the ERF actuator. The parameters of the fuzzy model are identified by using a hybrid neuro-fuzzy system. The fuzzy controller for vibration suppression of the composite beam designed is based on the fuzzy model by using modern control theory. The effect of the vibration control system with a fuzzy controller is verified by simulation and experiment.
