“…Griffo et al [6] injected a high‐frequency pulsating voltage signal into the estimated d ‐axis and subsequently demodulated the high‐frequency current response to estimate MM's rotor position. Maalouf et al [7] injected a high‐frequency rotating voltage signal into MM's stator, according to detecting MM's stator currents and subsequent current signal processing, MM's rotor position estimation can be realised. However, when WSSG starts the aero‐engine, the load characteristic of aero‐engine varies greatly, MM's stator current varies with it, which causes great change of MM's saliency (including decrease, disappearance and even reversal).…”

This study proposes a novel rotor position estimation method for wound-rotor synchronous starter/generator (WSSG). At the starting stage, WSSG needs a resolver to obtain the main machine's (MM's) rotor position. However, the use of resolver increases starting system's complexity, volume, weight and cost. In order to solve this problem, a novel kind of MM's rotor position estimation method is proposed, which considers the structure of WSSG as a resolver. The novel method injects a rotating voltage into MM's stator, detects main exciter's stator current and subsequently processes the current signals to estimate MM's rotor position. Experimental results show that the novel method can estimate rotor position accurately, which are in good agreement with the theoretical analyses and simulation results. Compared to the saliency tracking rotor position estimation method, the novel method does not rely on WSSG's parameters (including MM's saliency), and the signal processing procedures are more simple.
