崔顺实等人提出的反对派控制。采用直接数值模拟的方法研究了带宽受限和噪声污染对其控制性能的影响。结果发现，当控制方案被修改以考虑测量的传感器信号的对流速度时，传感频率可以显著降低。在较高的感知频率下，噪声传感器信号强烈影响可实现的净节能率和能量增益，而在较低的感知频率下，其影响较小。这些结果也适用于雷诺数的增加，其中控制方案的性能通常较低。
The opposition control proposed by Choi et al. is investigated using direct numerical simulation to see how bandwidth-limited and noise-contaminated sensing influence its control performance. It is found that the sensing frequency can be reduced substantially when the control scheme is modified to account for the convection speed of the measured sensor signal. Noisy sensor signals are shown to strongly affect the achievable net energy saving rate and energy gain at high sensing frequencies, while their influence is weaker for reduced sensing frequencies. These results also hold for increased Reynolds number, where the performance of the control scheme is generally lower.
