It is widely used in aerospace, industrial robots and other industrial applications. Because of its output analog signal, it has the advantages of high resolution, low cost, small size, and high dynamic performance. In practice, the resolver needs to be decoded by means of the decoder chip. However, when the resolver outputs a corresponding signal, the error signal will inevitably appear, and the decoder chip cannot effectively suppress the generation of this signal. In this paper, we aim to conduct a scientific and rational comprehensive research on the software decoding algorithms involved in several typical resolvers.At the beginning...
