摘要：

Position sensorless control for a commercially available squirrel cage synchronous reluctance machine is presented. The contributions of this paper are twofold. First encoderless position estimation for a squirrel cage synchronous reluctance machine using high frequency carrier signal injection is shown. The estimation accuracy and dynamic properties in particular at low speed have been investigated. Experimental results of a robust position estimation with a 4kW SyncRM are given. Second, a rather general approach to increase the SNR for small and noisy signal is presented. Especially for machines without a distinct saliency image, the low signal-to-noise ratio is problematic. Extract the desired signal and distinguish from unwanted frequencies is a precarious issue.
