Abstract: 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.
