- Abstract
To address challenges such as low starting torque and inaccurate position estimation in traditional sensorless control methods for switched reluctance motors (SRMs), this paper proposes a sensorless control strategy suitable for the startup and low-to-medium speed operation of multiphase SRMs. Firstly, an improved inductance calculation model for the pulse injection region is proposed based on the electromagnetic characteristics of SRM. Secondly, leveraging the results of the inductance model calculation, a three-phase commutation rule is designed to enhance the starting capability. Lastly, an adaptive angle tuning (AAT) module is devised to improve the phase commutation width, and the pulse injection region is optimized through a dynamic inductance threshold method. The efficacy of the proposed method was validated through simulations conducted on a prototype six-phase 12/10 SRM.
