摘要： A digital signal processor for closed loop velocity or position control receives sine winding output signals and cosine winding output signal from a resolver, digitizes the signals and outputs quadrature encoded signals to an excitation circuit. The excitation circuit is connected to an excitation winding in the resolver to provide signals for driving the resolver.

摘要： In a procedure for the digital evaluation of the analogue output signals from a resolver with at least two stator windings, arranged perpendicular to each other on a stator, and at least one rotor winding on a rotor able to rotate in relation to the stator, a sinusoidal signal is applied to the rotor winding and sine, respectively cosine shaped signals, depending on the angular position of the stator in relation to the rotor, are extracted from the stator windings. These signals are further processed after conversion into digital signals by application of the inverse tangential function, in order to compute an angular value for the relative angular position between the rotor and the stator. This angular value is affected by a propagation delay time error, which is compensated for by the introduction of a control loop. Because of the inclusion of the control loop, both the angular velocity of the rotor as well as its relative angular position can be obtained without degradation by propagation time delay errors.
