| Abstract |
Resolvers are widely used sensors for angular position feedback. Used in a digital feedback loop they require a resolver to digital converter (RDC). The digital signal processors (DSP) intended for digital control present constantly increasing computing possibilities and increasing number of integrated fuctions. This paper presents an investigation of the opportunity to implement as much of the converter as possible into a DSP. The paper first reviews the existing RDC methods and the recent publications on the subject. The most relevant methods are then considered to be implemented in both fixed and floating point DSP, and each of them is simulated using MATLAB and SIMULINK. The tracking loop method is implemented in an experimental set-up and the results are presented. |
