An adaptive backstepping PI sliding-mode control is proposed for speed control of the drive of an interior permanent magnet synchronous motor (IPMSM) subjected to load disturbances. First, a nonlinear model with uncertainties is derived for the IPMSM, and then an adaptive backstepping sliding-mode controller incorporating a linear load torque estimator is(More)
This paper presents a novel sensorless drive method of the Axial flux permanent magnet (AFPM) brushless direct current (BLDC) motors by detecting zero-crossing points of back electromotive force signals from the standstill state to the desired velocity. A soft-switching mechanism is combined with the sensorless drive approach to achieve low electronic noise(More)
In this study, we propose a current-sensor-based predictive current control (CSBPCC) for six-switch three-phase (SSTP) inverter-fed synchronous reluctance motor (SynRM) drives. Generally speaking, two current sensors are used for detection of a- and b-phase stator currents of a SynRM drive system, respectively. In each sampling interval, the stator current(More)
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, 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)
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)
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)
