In a sensor less control method using the high-frequency fluctuating voltage signal injection to the estimated d axis as described in Section 6.4.2.2, derive the high-frequency component current at the q axis of the estimated d-q axis in terms of SMPMSM parameters and angle error under the assumption of small enough angle error. The injected high frequency signal is represented as (6.81) [62]
