Abstract
According to one aspect, a resolver-to-digital converter includes a first filter configured to receive a first delta-sigma modulated resolver input. A second filter is configured to receive a second delta-sigma modulated resolver input. A summing junction is configured to output a difference between a scaled output of the first filter and a scaled output of the second filter. A controller is configured to generate a controller output based on a product of a demodulator and an output of the summing junction. An integrator is configured to generate an estimated position based on the controller output. The resolver-to-digital converter also includes a compensator configured to generate a compensated estimated position based on the controller output and a compensation offset delay adjustment.
