| 摘 要： | 电流变液作为一种智能材料在振动控制工程领域有着广泛的应用。由于电流变效应具有非线性特性，使得难以设计基于常规控制理论的控制律。本文利用模糊逻辑系统能够逼近非线性函数的特性，设计了电流变阻尼器－转子振动系统自适应模糊控制方案。针对该转子系统的仿真计算表明，转子系统的振幅能够得到有效的抑制，自适应模糊控制器性能良好。

| Abstract: | Electro-rheological(ER) fluids have extensive application in the field of vibration control as a kind of intelligent materials.It is very difficult to develop a conventional control system due to the nonlinearity of the ER effect in regard to electric field strength,temperature or shear rate.An adaptive fuzzy control system is composed of a structural identification system and a controller system,and introduced for the ER damper-rotor vibration system due to the function approximator property of fuzzy logical system.A numerical study indicates the validity of the adaptive algorithm and the effective suppresion of the rotor vibration. |
