TMS320F240 DSP Solution for Obtaining Resolver Angular Position and Speed
This application report presents a TMS320F240 DSP solution for obtaining the angular position and speed of a resolver. A resolver is an absolute mechanical position sensor used, for example, in servo applications. It is basically a rotating transformer. The sinusoidal input reference is amplitude modulated with the sine and cosine of the mechanical angle, respectively. These two output signals have to be decoded to obtain the angular position.
