A Novel Single-Phase Current Sensor Control Strategy Based on Dual APF-QSG for Position-Sensorless IPMSM Drives
IEEE TRANSACTIONS ON POWER ELECTRONICS(2024)
摘要
This letter proposes a novel single-phase current sensor (SPCS) control strategy for position-sensorless interior permanent-magnet synchronous motor drives. In the proposed strategy, two all-pass filter-based quadrature signal generators are employed to independently reconstruct the respective quadrature signal of the equivalent back electromotive force. A position estimation scheme using an SPCS is developed, and the current information for feedback is further obtained by the proposed quadrature current reconstruction scheme. The proposed strategy is validated through a sequence of experimental evaluations.
