摘要：
A sensorless control method for switched reluctance motor (SRM) based on line inductance feature point positioning is proposed to solve the problem of low accuracy of rotor position estimation due to saturation of magnetic circuit. First, the basic concepts of line inductance and its feature points are proposed, and the function relationship between line inductance and rotor position is analyzed. The method of estimating the average rotor speed and the position of the next corresponding interval based on the position and time of the corresponding interval of the feature points of two adjacent lines inductance is studied. Finally, the feasibility of the above method is verified by simulation and experiment. © 2020, Editorial Department of Control Theory & Applications South China University of Technology.
