Abstract :
Given the characteristics of MW-level direct-drive permanent magnet synchronous generator (PMSG), a simple sensorless low-pass-filter-compensation-integrator (LPFCI)-based rotor flux position estimation control method is proposed. Its implementation principle is introduced in detail. Furthermore, saturation feedback double integrator based on coordinate transform (SFDICT) and LPFCI are discussed in depth. Finally, simulation and experimental results indicate the feasibility of the method.
