The paper describes an investigation of fault tolerant control strategies for permanent magnet synchronous motor (PMSM) driven by a fault-tolerant inverter. The inverter is a topology-modified inverter with fault-tolerant capability, which can be configured as the standard 3-phase 6-switch inverter and reconfigured as 3-phase 4-switch or 2-phase 4switch inverter under the fault condition. By an...

This paper presents a comparative study on two most popular control strategies for Permanent Magnet Synchronous Motor (PMSM) drives: field-oriented control (FOC) and direct torque control (DTC). The comparison is based on various criteria including basic control characteristics, dynamic performance, and implementation complexity. The study is done by simulation using the Simulink Power System B...

Sharp LC resonance peak may enlarge inherent harmonics, dominant harmonics of the supply voltage generated by a three-phase diode rectifier, around frequency, which will intensify fluctuations dc-link voltage, and grid currents in motor drives with small capacitor. In this article, novel suppre...

In this paper, a sensorless permanent magnet synchronous motor (PMSM) drive was presented based on calculating the back EMF using reference stator voltages, which are output of d-axis current controller, includes information about rotor position. Sensorless control estimates position necessary for vector without sensor or encoder. This can provide effects such as increased system reliability an...

In this paper, the driver with antiwindup and fuzzy high-performance and robust PI controller has been suggested for Permanent Magnet Synchronous Motor (PMSM). This controller is suggested for the design of the robust driver for three phase PMSM and the cost reduction of its control system. It’s useful for the industrial application and automation and ultimately speed control and the improvemen...

<p>This paper describes a novel fuzzy tracking control for permanent magnet synchronous motors (PMSM) using an extended Kalman filter (EKF) and disturbance observer (DO). The goal is to create robust controller able drive the system’s states track virtual reference model provide low effect on machine. First, PMSM represented Takagi-Sugeno (T-S) attended by load torque variation. Next, To ...

In this paper, a current sensor fault detection mechanism based on multilayer perceptron (MLP) in permanent magnet synchronous motor (PMSM) drive system is presented. The solution for the PMSM was previously described and tested only simulation studies. application allows of basic faults (lack signal, gain error, signal noise) sensors indication phase (A or B) which occurred. work focused analy...

This article presents a multiple-vector finite-control-set model predictive control (MV-FCS-MPC) scheme with fuzzy logic for permanent-magnet synchronous motors (PMSMs) used in electric drive systems. The proposed technique is based on discrete space vector modulation (DSVM). converter’s real voltage vectors are utilized along new virtual to form switching sequences each sampling period order i...
