摘要
要感应电机定子电阻瞬时值受诸多因素的影响，且无法建立精确的数学模型去求解。文中设计了一种模糊在线检测器以检测电阻的瞬时值，为改善直接转矩伺服系统的低速性能找到了一种有效的方法。实测表明该模糊检测器检测误差在工程允许范围内。
The stator resistance of an induction motor is affected by many different elements, and the exact math model can not be established for calculation of the instantaneous resistance. This paper designs a fuzzy observer for measuring resistance value of induction motor and presents an effective method for improving the performance of the DTC servo system at low speeds. The observation error can meet the needs of the DTC system.
