Adaptive control, which is capable of accommodating system parametric, structural, and environmental uncertainties, is a suitable choice for such actuator failures compensation schemes.

自适应控制对这样的驱动器故障补偿方案是一个合适的选择，它能够适应系统参数、结构和环境的不确定性。

Strictly speaking, the structural parameter and outside-load all have errors or uncertainties to a certain extent, especially the load uncertainty.

从严格意义上说，结构参数和载荷(特别是载荷)都具有某种程度上的误差或不确定性。

However, I fully agree with Tom's comment that we don't want to do anything to "steal the thunder" from ongoing efforts to improve sonde-based estimates of atmospheric temperature change, and to better quantify structural uncertainties in those estimates.

While inclusion of a Figure 4 is not essential for the purpose of illuminating the statistical flaws in the Douglass et al. "consistency test", such a Figure would clearly show the (currently large) structural uncertainties in radiosonde-based estimates of the vertical profile of atmospheric temperature changes.
