Review of RDC Soft Computing Techniques for Accurate Measurement of Resolver Rotor Angle
نویسندگان
چکیده
A resolver is a position sensor or transducer that measures the instantaneous angular position of the rotating shaft to which it is attached. Resolver produces two amplitude modulated signals; SIN and COS as output signals. These two signals need to be demodulated and converted to digital signals before they can be used for control. There are several techniques available in the literature to measure the rotor shaft angle. This paper focuses on the design of both hardware and software based resolver to digital converter (RDC) techniques available in the literature. This literature review helps the researchers to know about all these methods and plan future work on RDCs to improve the angle tracking performance. Copyright © 2013 IFSA.

The importance of reliability make resolvers key building block in flight control and navigation dynamics. The resolvers provide electrical signals related to the sine and cosine of the mechanical shaft angle θ. An analog converter is described for the linearization of these signals and hence for linear computation of θ. The converter was based upon the difference between the absolute values of...

متن کاملA Comprehensive Mathematical Model for Analysis of WR-Resolvers under Stator Short Circuit Fault
Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...
