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。
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。
