actual observed value

基本解释

Because of many reasons in the course of straightness error measuring, many original observed data deviate from actual value and are difficult to process.
由于在直线度误差测量过程中的各种原因，导致许多观测数据与实际值偏离或者很难进行处理。
When the estimated speed converges to the actual rotor speed, the rotor flux observed converges to its true value, which can be used in direct field orientation control(DFOC).
当电机转速的估计值收敛于转速的真实值时，观测的转子磁链也收敛于其真实值，可将其用于直接磁场定向控制中。
Comparing the results with the observed value of ionosonde measured in Wuhan, we find that this model can objectively describe the actual situation in the mid-latitude ionospheric E layer.
将模式的计算结果与武汉地区测高仪的观测数据进行比较，结果证明模式能够较为客观地反映中纬电离层E层的实际形态。
