- Abstract
- This paper proposes the phase delay compensation method of the analog filter used to enhance the measuring performance for sensorless control based on high frequency signal injection. An inherent delay effect caused by a band-pass-filter has a negative impact on the position estimation for a signal injected sensorless control, and thus requires a proper compensation. In this paper, the delay effect is investigated theoretically, and its compensation method is proposed. Several verifications by the simulations is presented.
