Rotor position estimation of wound‐rotor synchronous starter/generator
The Journal of Engineering, 2018 This study proposes a novel rotor position estimation method for wound‐rotor synchronous starter/generator (WSSG). At starting stage, WSSG needs a resolver to obtain main generator (MG)'s rotor position. However, the use of resolver increases starting system's complexity, volume, weight and cost. In order to solve this problem, a new kind of MG's rotor
