本文提出了一种结合线性和非线性速度反馈控制的方法来抑制柔性悬臂梁结构的主参数共振。采用线速度反馈进行分岔控制，采用双速度反馈抑制高幅值振动。数值仿真和实验结果表明，分叉控制和非线性反馈控制相结合，可以避免执行器饱和，比单独的线性速度或非线性速度反馈控制提供更好的性能
In this paper, a control method that combines linear and nonlinear velocity feedback control is proposed to suppress the principal parametric resonance in a flexible cantilever beam structure. Linear-velocity feedback is employed for bifurcation control and cubic-velocity feedback is employed to suppress the high-amplitude vibration. Numerical simulation and experimental results show that combined bifurcation control and nonlinear feedback control can avoid actuator saturation and provide better performance than linear-velocity or cubic-velocity feedback control alone
