This paper presents the high frequency (HF) pulsating injection method based sensorless control combined with model predictive current control (MPCC) for permanent magnet synchronous motor (PMSM). The use of MPCC makes the implementation of sensorless algorithm difficult due to the lack of a modulator. Therefore, HF current signal is injected instead of normal voltage signal, which is more suitable for MPCC rather than filed orient control (FOC). Besides, three-vector-based MPCC is utilized, which can reduce the current ripple effectively and improve the steady-state performance. Finally, simulation results demonstrate the feasibility and effectiveness.
