This study proposes a sensorless speed-control system for a DC-link capacitorless inverter-based interior permanent magnet synchronous motor (IPMSM) drive system via measuring switching-state current-ripples. By measuring the current-ripple of each pulse-width modulation switching-state, the rotor position of the IPMSM can be estimated. As a result, the hardware of a high-frequency sinusoidal voltage...
This paper proposes a dual current-slope rotor position estimation and its relative sensorless closed-loop drive system for synchronous reluctance motors. First, the mathematical model of the synchronous reluctance motor is discussed. Then, a new rotor position/speed estimator of the synchronous reluctance motor is proposed. The proposed method uses dual current-slope to estimate the rotor position...
This paper proposes a novel high-performance rotor position estimator for an interior permanent magnet synchronous motor. By suitably processing the mathematical model of the motor, a systematic method of the rotor position estimating method has been developed. The proposed control system can be used in the space vector pulse-width-modulation switching method. By measuring the dc-bus voltage and the...
This paper proposes a novel sensorless position control system for an interior permanent magnet synchronous motor. In this paper, a novel rotor position estimation technique is proposed. This estimation technique only relates to the slopes of the three-phase stator currents, and does not relate to the parameters or operating conditions of the motor. Neither extra circuit nor external exciting signal...
