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。
An actual example demonstrated its feasibility. This algorithm had fast speed of convergence and good stability and no demand of initial value.
最后经一实例计算说明该算法的可行性，该算法具有对初始值要求不高、收敛速度快，稳定性好的特点。
