摘要
反馈环节的时滞会导致受控系统失稳，制约着振动主动控制技术的发展和应用。本文概述了作者近期对含时滞振动控制系统动力学的研究，包括：线性单自由度时滞系统的稳定性判据，线性多自由度小时滞系统的稳定性分析方法，Ｄｕｆｉｎｇ时滞系统的主共振与亚谐共振分析，时滞系统周期运动及稳定性的数值分析等。最后，指出了值得研究的一些问题。
Time delays in feedback control may result in the unstable motion of a controlled vibrating system,and hence limit the development and application of vibration control.In this paper summarized are the recent sutdies of the author on the dynamics of controlled systems with time delay feedback. They include the stability criteria for linear SDOF systems with delay feedback,stability analysis of linear MDOF systems with short delay feedback,the primary resonance and subharmonic resonance of harmonically forced Duffing oscillators with delay feedback,and the numerical analysis of the periodic motions and their stability of nonlinear systems with delay feedback.A number of open problems are finally pointed out.
