摘要： 研究非线性振动系统中混沌的开闭环控制问题.对于单自由度混沌振动系统建立了开闭环控制律.以受迫Duffing振子为数值算例,说明了该控制律的有效性和鲁棒性.将该控制律推广到多自由度混沌振动系统.

关键词: 非线性振动, 混沌, 开闭环控制

Abstract: The open-plus-closed-loop control of chaos in nonlinear oscillating systems is investigated in this paper.The open-plus-closed-loop control law for sing le-degree-of-freedom chaotic oscillations is established.The forced Duffing oscillator is treated as a numerical example to demonstrate the effectiveness and robustness of the control law. The control law is also extended to multi-degree-of-freedom oscillating systems.

Key words: open-plus-closed-loop control, nonlinear oscillation, chaos
