Sensorless Method Research for SRM Based on ANFIS

The position estimation training model based on ANFIS for SRM has characters with a clear hierarchy, fast training, etc., but less the estimation accuracy when SRM line to the saturation region. Based on the SRM model by careful analysis and simulation, this paper proposes a uniform speed position detection method for SRM of Single-phase conduction on-line to the saturation region, and makes the saturated region boundary as the switching point to combine the established position estimation model based on ANFIS to the uniform speed position detection method, for SRM of high-precision indirect detection in the whole angel cycle. To 8/6 phase SRM, for example, simulation results prove the method with characters of real time and efficiency.
