“…In a real system, the resolver output signals contain position errors in the resolver itself as well as in the resolver signal processing circuits [10]- [14]. As a result, the actual resolver output signals have non-ideal characteristics, such as offset error, scale error, or phase error.…”

“…The proposed method in [13] was only presented to integrate the ideal rotor position and obtain the magnitude of the position error according to the distorted rotor position because of amplitude imbalance, without considering the variation of the rotor speed and bandwidth of the closed-loop current control. A method to reduce torque ripple caused by amplitude imbalance is introduced in [14]. This method required an additional position sensor that has no distorted position information to reduce torque ripples.…”

This study proposes a classification and compensation algorithm of two non-ideal output signals of a resolver to reduce position errors. Practically, a resolver generates position errors because of amplitude imbalance and quadrature imperfection between the two output signals of the resolver. In this study, a digital signal processor system based on a resolver-to-digital converter is used to reconstruct the two output signals of the resolver. The two output signals, "sin" and "cos," can be represented by a unit circle on the xy-plot. The classification and compensation of the errors can be obtained by using the radius and area of the circle made by the resolver signals. The method computes the integration of the areas made by the two resolver output signals to classify and compensate the error. This system cannot be applied during transient response given that the area integration during the transient state causes an error in the proposed method. The proposed method does not need any additional hardware. The experimental results verify the effectiveness of the proposed algorithm.

-Resolvers are transducers that are used to sense the angular position of rotational machines. The analog resolver is necessary to use resolver to digital converter. Among the RDC software method, angle tracking observer (ATO) is the most popular method. In an actual resolverbased position sensing system, amplitude imbalance dominantly distorts the estimate position information of ATO. Minority papers have reported position error compensation of resolver's output signal with amplitude imbalance. This paper proposes new ATO algorithm in order to compensate position errors caused by the amplitude imbalance. There is no need premeasured off line data. This is easy, simple, cost-effective, and able to work on line compensation. To verify feasibility of the proposed algorithm, simulation and experiments are carried out.
