摘要
针对结构振动的反馈控制方法，考虑作动器的动态特性，给出保证位移正反馈、速度负反馈和加速度负反馈控制稳定的时延界限和增益幅度．比较了三种反馈方法的优缺点，指出加速度负反馈具有大范围的稳定特性．
Three kinds of methods for the control of structural vibration are discussed in this paper with the dynamic characteristics of actuator taken into consideration. Constraint conditions for the stable control of structural vibration are given according to positive position feedback control, direct velocity feedback control and acceleration feedback control. The comparison of the three feedback control methods shows that the direct acceleration feedback can ensure more stable control of structural vibration.
