In the field of closed loop controlled voltage source inverter fed induction machines the rotor field oriented control (RFOC) with direct or indirect current control is the most used control scheme. It can be regarded as state of the art for various applications [1], [2]. A high performance rotor flux oriented speed sensorless indirect vector-controlled induction motor drive is described in the paper. The effectiveness of the proposed system is verified by computer simulation.
