| 摘 要： | 对旋转运动柔性梁的时滞主动控制进行实验研究，验证时滞反馈控制的有效性. 实验中采用交流伺服电机带动柔性梁旋转运动，柔性梁上粘贴有压电作动器，用于控制梁的弹性振动. 实验研究考虑如下3种情况:(1)仅使用电机扭矩进行控制，电机扭矩存在时滞；(2)使用电机扭矩和压电作动器同时控制，仅压电作动器存在时滞；(3)使用电机扭矩和压电作动器同时控制，电机和压电作动器存在不同的时滞量. 重点通过实验验证时滞反馈控制的可行性和有效性.

| Abstract: | In this paper, active control of a rotating flexible beam
with time delay is experimentally investigated. A servo motor is used to
drive the beam in a rotating motion and a piezoelectric (PZT) actuator
sticked on the beam is used to control the beam in the elastic vibration.
Three experimental cases were performed, that is, (1) only with the servo
motor for active control and the time delay only for the motor; (2) with the
servo motor and PZT actuator for active control and the time delay only for
the PZT actuator; (3) with the servo motor and PZT actuator for active
control and the time delay only two all. The experimental results
demonstrated the feasibility and effectiveness of time-delay feedback
controller. |
