This paper deals with a new method current sensors faults detection isolation (FDI) and reconfiguration of the control loops of a permanent magnet synchronous motor (PMSM) drives. The stator currents are measured as well as observed. During fault free operation, the measured signals are used for the PMSM control. In the case of current sensors faults, the faulty measurements are detected and isolated using the new FDI algorithm. This algorithm uses an augmented PMSM model and a bank of adaptive observers to generate residuals. The resulting residuals are used for sensor fault detection. A logic algorithm is built in such a way to isolate and identify the faulty sensor for a stator phase current fault after detecting the fault occurrence. After sensor fault detection and isolation, the control is reconfigured using the healthy observer's outputs. The validity of the proposed method is verified by simulation tests.

“…In Trabelsi, a PWM‐based fault detection method employed to detect faults in a power converter is proposed, which is performed by analyzing the switching pulses and the voltage levels in healthy and faulty modes. In Shahbazi et al, a voltage observer used to detect faults for DFIG‐based wind system is proposed, which is performed by using a “time and voltage criterion”.…”

Summary This paper addresses the diagnosis of open‐switch fault in pulse‐width modulation (PWM) power converter based on insulated‐gate bipolar transistor (IGBT) used in doubly‐fed induction generator‐direct current (DFIG‐DC) system. The fault diagnosis is carried out by analyzing the rotor currents within healthy and faulty operation conditions. In the new proposed configuration of DFIG connected to DC‐bus, the diode rectifier is employed to connect the stator windings to the DC‐bus and the PWM power converter is employed to connect the rotor windings to the DC‐bus. The main goal of using a PWM power converter is to keep the stator voltage and frequency constant at rated values. In this regard, the various experimental results for open‐circuit faults are obtained by using dSpace DS1104 control board. Some experimental results are obtained, proving the effectiveness of the proposed diagnosis approach such as low detection time and high robustness against false alarms.

“…Techniques based on analysis of the signals require the measurement of inverter outputs currents or voltages. Methods based on voltage analysis, as addressed in [14]- [19], have a major drawback because an extra hardware or M extra sensors are usually needed for real time implementation. Methods based on current signals have been reported in [16]- [20] to multiple open-switch fault.…”
