Abstract

A sensorless drive of induction motor has several advantage: low cost and availability in a harsh environment. Most of sensorless control schemes are based on the direct estimation of rotor speed from state observer. This study proposes a new sensorless control scheme. The proposed scheme is based on a reference model control which the error between the model and plant outputs decays to zero as time proceeds. The actuating signal is calculated from the fuzzy controller which increases the system stability and robustness. The simulation results indicate a good dynamic performance.
