基于控制的延拓是一种最近开发的方法,用于以受控方式测试非线性动态系统并探索其在系统参数变化时的动态特征。在本文中,基于控制的延拓用于在实验中直接跟踪具有软化-硬化恢复力的单自由度振荡器的稳态周期解。研究了振荡器的受迫响应,并在受迫幅度和频率方面充分表征了振荡器的受迫响应。然后,通过遵循振荡器响应和基础激励之间的相位正交条件,在实验中直接提取振荡器的主干曲线。
Control-based continuation is a recently-developed approach for testing nonlinear dynamic systems in a controlled manner and exploring their dynamic features as system parameters are varied. In this paper, control-based continuation is used to track directly in the experiment the steady-state periodic solutions of a single-degree-of-freedom oscillator presenting a softening-hardening restoring force. The oscillator forced response is investigated and fully characterized in forcing amplitude and frequency. The oscillator’s backbone curve is then extracted directly in the experiment by following a phase quadrature condition between the oscillator response and the base excitation.
