基于控制的延拓是最近开发的一种方法，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，基于控制的延拓适用于跟踪系统响应和激励正交的轨迹，提取底层保守系统的主干曲线。该方法应用于基极激励下的单自由度振荡器，并将结果与标准谐振衰减法进行了比较。
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 adapted to follow the locus where system response and excitation are in quadrature, extracting the backbone curve of the underlying conservative system. The method is applied to a single-degree-of-freedom oscillator under base excitation, and the results are compared with the standard resonant-decay method.
