| 摘 要： | 针对大型智能桁架结构的振动抑制问题,采用扩张状态观测器(ESO)和非线性状态误差反馈控制律(NLSEF),设计了不依赖于模型的自抗扰振动控制器。然后,基于dSPACE实时仿真系统,建立了102杆三棱柱压电智能桁架结构的主动振动控制试验系统,进行了自抗扰振动控制实验。结果表明:自抗扰振动控制器可有效地用于压电智能桁架结构的振动控制,低频谐振控制实验振幅降低了81.5%,取得了良好的控制效果。

| Abstract: | An auto disturbance rejection vibration controller(ADRVC)was designed using an extended state observer(ESO)and nonlinear state error feedback control(NLSEF).Then,dSPACE simulations were used to model the vibration control of a 102-bar triangular prism piezoelectric intelligent truss structure using the auto disturbance rejection vibration control.The results demonstrate that the controller can effectively control the vibrations of the piezoelectric intelligent truss structure.The vibration amplitudes are re... |
