摘要
The paper proposes a sensorless technique for standstill self-commissioning of synchronous reluctance machines. Previous works have demonstrated the potential of simultaneous excitation of d and q axis with hysteresis square-wave voltage injection for the exploration of current plane with insignificant rotor movement. The proposed structure retains the hysteresis control for q axis while i(d) is closed loop controlled using a weak PI regulator. Akin to the parking technique, a DC current is imposed in a fixed reference frame to inhibit any rotor movement and realize the self-locking mechanism. This permits systematic inspection of the dq current plane for accurate cross-saturation modeling. In addition, a new approach for the identification of cross-saturation in d axis from the high frequency component in i(d) current is developed. The experimental tests on 1.1 kW synchronous reluctance motor test bench prove the validity of proposed technique.
