In this study, a model-free predictive current controller (MFPCC) for four-switch three-phase (FSTP) inverter-fed interior permanent magnet synchronous motor (IPMSM) drive systems is proposed. A new method, using the stator current and its difference is proposed to predict the next stator current. The advantages of the proposed MFPCC are low computation,(More)
In this paper, a sensorless position control for four-switch three-phase (FSTP) inverter-fed interior permanent magnet synchronous motor (IPMSM) drive systems is proposed and studied. Unlike traditional sensorless position controls that are based on zero-voltage switching mode generated by a six-switch three-phase (SSTP) inverter, the proposed method(More)
In this paper, we propose a model-based predictive current control (MBPCC) scheme for four-switch three-phase (FSTP) inverter-fed interior permanent magnet synchronous motor (IPMSM) drive systems based on a three-phase extended back-EMF estimation method. First, we estimate the three-phase extended back-EMFs of IPMSM using the information of the stator(More)
An improved predictive current control for interior permanent magnet synchronous motor (IPMSM) drive systems using current difference detection technique is proposed in this paper. First, a conventional model-based predictive current control for IPMSM is introduced, which needs the information of the resistance, q-axis inductance, and extended back-EMF of(More)
