要約(英語): This paper presents the position sensorless control of a switched reluctance motor (SRM). Position estimation accuracy is dependent on the measurement accuracy of the differential current, which is typically measured by dividing the difference between two sampled currents by the sampling period. The division error increases at a high carrier frequency because the sampling period is short. In this study, an analog circuit of a type-1 control system was utilized to reduce the error. The type-1 control system is a stable feedback loop with a first-order integrator element. When the current is input to the analog circuit, the output signal of the integrator converges to the current and the input signal of the integrator is measured as a differential current. Therefore, the differential current is directly measured without the division. The experimental results confirm the effectiveness of the proposed method.
