The aim of this research is to present a new method for the selection of position sensor resolution in variable speed drives. The proposed approach links the minimum sensor resolution Nds to the required drive performances, expressed in terms of desired quantization speed harmonics attenuation and speed control loop bandwidth, both defined at the minimum requested operating speed. Although the selection of rotor position sensor resolution is presented for a vector tracking observer, this approach is general and can be used in conjunction with the operating point model of any speed estimation algorithm. Simulations and experimental results validate the effectiveness of the proposed method.

Abstract

The aim of this research is to present a new method for the selection of position sensor resolution in variable speed drives. The proposed approach links the minimum sensor resolution Nds to the required drive performances, expressed in terms of desired quantization speed harmonics attenuation and speed control loop bandwidth, both defined at the minimum requested operating speed. Although the selection of rotor position sensor resolution is presented for a vector tracking observer, this approach is general and can be used in conjunction with the operating point model of any speed estimation algorithm. Simulations and experimental results validate the effectiveness of the proposed method.
