Experimental Realization- Real-Time Implementation- Switched Reluctance Motor (SRM)- current control strategyAbstract
This paper presents an improved current control strategy for a switched reluctance motor (SRM) drive. Owing to its doubly salient structure and nonlinear magnetic characteristics, the SRM exhibits strong coupling between current, flux, and torque, making accurate current regulation essential for achieving stable torque production and minimizing acoustic noise and ripple. The proposed controller is designed to enhance current tracking accuracy under fast dynamic conditions while preserving robustness against magnetic saturation, inverter delays, and load disturbances. Experimental validation is conducted on a fully instrumented SRM test bench using real-time acquisition hardware and a standard asymmetric bridge converter. The study demonstrates significant improvements in current tracking, torque quality, energy utilization, and global operational reliability when measured against earlier approaches in the literature.
Highlights
- Significantly improved current-tracking performance with reduced dynamic error.
- Enhanced torque quality, including lower ripple and smoother torque production.
- Increased overall energy efficiency of the drive system.
- Improved operational reliability compared to conventional controllers reported in previous studies.
- The proposed solution outperforms existing methods in terms of accuracy, robustness, and overall performance.
