摘要
以异步电机的等效电路为模型提出了在电机的外部构造转子磁链物理观测器的方法.理论上证明了在选取合适参数之后,用该物理观测器可以直接得到感应电机转子磁链的大小与相位,该方法用于异步电机的矢量控制系统,具有很好的实时性,且避免复杂的数字运算.
A method of constructing physical observer of rotor flux linkage, generally used in vector control system of induction motor, is presented by comparing to equivalent circuit of induction motor. It is proved that if the parameters of the observer are properly chosen, the value and position of rotor′s flux linkage can be obtained directly outside of the motor. This method has advantage of real\|time and could avoid complex digital calculation.
