This paper presents an investigation of an inverter fault tolerant direct torque control (DTC) of permanent magnet synchronous motor (PMSM) with loss of one leg. In case of faulty inverter, continuous operation is necessary and thus a breakdown of the PMSM drive is unacceptable. The basic idea of this work consists in analyzing performance of a three legs inverter and two legs inverter fed PMSM drive...
this paper proposes a fault tolerant control (FTC) for permanent magnet synchronous motors (PMSM) using field-oriented control (FOC) and direct torque control (DTC) strategy. In order to ensure continuity of operation and without losing PMSM performance in fault, the proposed FTC allows transition from FOC to DTC. The FOC of PMSM drive needed a mechanical sensor to measure rotor position but with...
The aim of this article is to present the performance of field oriented control (FOC) and direct torque control (DTC) of a permanent magnet synchronous motor (PMSM) using the technique of space vector pulse width modulation (SVPWM). First, after developing a mathematical model of PMSM we present the principle of space vector modulation technique to use in commands. Secondly, we developed a field oriented...
This paper proposes a sensorless speed control strategy for a permanent-magnet synchronous motor (PMSM) based on a sliding-mode observer (SMO). In order to apply a sensorless PMSM control which is robust against parameter fluctuations and disturbances, a high-speed SMO is proposed, which estimates the rotor position and the angular velocity. The stability of the proposed SMO was verified using the...
Permanent Magnet Synchronous Motors (PMSM) are many used to high performance applications. Accurate faults detection can significantly improve system availability and reliability. This paper investigates the experimental implementation and detection of open phase faults in interior permanent magnet synchronous motor (IPMSM). The proposed method of open phase fault detection is based only on stator...
