摘　　要：本文设计了一种定子电阻模糊控制辨识器,并通过仿真对电机的定子电阻进行在线辨识研究,结果表明该辨识器可以得到与实际电阻十分接近的值,带有该辨识器的直接转矩控制系统具有定子磁链观测精度较高,电机运行更加平稳,输出转矩脉动小,系统鲁棒性较好等特点。This paper has designed a fuzzy observer for measuring stator resistance value of induction motor and carries on on-line through the simulation to observe stator resistance of the induction motor. The simulating result is presented to demonstrate the observer can obtain the extremely close value as the actual resistance. The Direct Torque Control system with the stator resistance observer has many advantages such as the stator flux linkage observation precision high, electrical machinery movement steadier, output torque pulsation small, system robustness is better etc.
