V/f Control for Switched Reluctance Motor

This paper proposes a novel V/f control method for a switched reluctance motor (SRM). The proposed method does not require the rotor position information and the nonlinear magnetization curve model of SRM. A virtual rotor magnetic flux is generated by controlling the zero-phase current with a PI controller, which realizes the V/f control for SRM. In addition, the maximum torque / current ratio control is achieved by the reactive power in the V/f control. In the proposed simple speed control without a position sensor, the current RMS value is reduced by 43.9% at the torque of 0.1 p.u. compared to without high-efficiency control.
