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
