桁架结构主被动振动控制的时间延迟分析与预估计补偿法

时间延迟是实时振动控制迫切需要解决的问题，以主被动控制组合式桁架结构为研究对象，分析了延迟对实时控制的影响，论述了延迟时间的测定，提出了一种有效的延迟补偿方法。通过一个平面桁架算例验证了该补偿方法的有效性，定量分析了相位滞后与控制效果的关系。

Study of Time Delay in Active-Passive Vibration Control of Truss Structure and Time Delay Compensation

Time delay is an important problem that should be well solved in the active vibration control. Based on the study of complex truss structure with artive and passive control members ,this paper has discussed the affection of the time delay to vibration control, proposed a way to measure the time delay and a method of time delay compensation. Us- ing an example of plane truss srtuctme, the method is well proved, and the relationships between the phase delay and control are also discussed.
