title = "A resolver-To-digital conversion system based on second order Butterworth low pass filter",
abstract = "Resolvers exhibit relatively impressive ruggedness, high accuracy, strong anti-interference ability and wonderful reliability in many household and industrial applications. However, it is necessary to use Resolver-To-Digital Conversion (RDC) to get the position and speed from the resolvers, due to the analogue output of resolvers. In this paper, an RDC system with excellent performance is proposed based on frequency shifting method by using Butterworth low pass filter and type-II Angle Tracking Observer (ATO) to estimate resolver shaft angle. Because of the outstanding frequency response characteristic of Butterworth filter, lower phase delay, more sufficient bandwidth and higher accuracy can be achieve compared by traditional RC filters. Eventually, both simulations and experimental results validate the effectiveness and feasibility of the proposed method.",
