“…Recently, SCM has been modified and utilised in the analysis of electrical machines of special designs and/or under fault conditions. For example, the analysis of unbalanced operation of 5-phase induction machines is presented in [6] and the performance of a class of 5-phase permanent-magnet synchronous-reluctance motors is evaluated, with one open phase, in [7]. The method has also facilitated development of fault signature analyses of both synchronous and induction machines [8]- [10].…”

Although the method of symmetrical components is commonly used in investigating unbalanced operation of electrical machines and power systems, its application in the analysis of transient behaviour of electrical machines can be advantageous. The main advantage lies in the ease with which different fault conditions can be analysed. In this paper, the differential equations describing an induction machine are developed in terms of the symmetrical components of the instantaneous values of transient voltages and currents. The developed model enables investigation of various fault conditions when the machine is operating as a motor or a generator.

“…Among existing FDI presented in [15]- [17], the present FDI belongs to the family of signal based methods as reported in [19], [21], [25] and [26] which are distinguished with the model based methods as in [27]- [28]. More precisely the FDI is using the currents and not the voltages whose measured real values are difficult to use because the Voltage Source Inverter (VSI) are controlled by PWM.…”

This paper investigates a real-time fault diagnostic of a transportation system which needs two drives with faulttolerance capabilities. Because of constraints on the mass of the system and on the cost of the Voltage Source Inverter (VSI), a drive with two Six-Phase Permanent Magnet Synchronous Machines (PMSM) in series-connection supplied by two six-leg inverters is chosen. Despite the serial -connection, independent control of the two machines and fault -tolerance to openswitch fault is ensured. Nevertheless, a Fault Detection Identification (FDI) process is required for analysis and/or control reconfiguration. The proposed FDI is based on the combination of different criteria obtained from the two zero-sequence currents and from the normalized currents mapped into two frames defined by the Concordia Transformation. Results obtained from simulation and experimental tests show the effectiveness of the proposal.

“…Keeping these applications in mind, several recent works have focused on the development of high-performance, fault-tolerant control schemes for induction machines (IMs) and permanent magnet synchronous machines (PMSMs) [4][5][6][7]. The diagnoses focus on rapidity and accuracy [8,9], and adoption of effective isolation measures, such that a corresponding fault-tolerant control scheme can be adopted. The important goal of a fault-tolerant control strategy is to be able to maintain the normal index operation effectively and stably after fault isolation.…”

Unified Fault-tolerant Control Strategy with Torque Ripple Compensation for Five-phase Permanent Magnet Synchronous Motor Based on Normal Decoupling

et al. 2019

View full text Add to dashboard Cite

In this paper, the decoupling matrix in a five-phase permanent magnet synchronous motor (FPMSM) is rebuilt and changed, according to different open-phase conditions, which complicate the switch and control algorithm. This paper proposes a unified fault-tolerant control strategy with decoupling transformation matrix, effectively suppressing the torque ripple for several open-phase faults. The current algorithms for different open-phase faults are demonstrated; torque ripple, especially, is analyzed with third harmonic magnetomotive force (MMF). The unified current control law is expressed with two adjustable coefficients, which are regulated for torque ripple compensation. As the current control equation remains unchanged, the fault-tolerant can smoothly switch from normal to fault condition, only with different coefficients. The proposed method with torque compensation (TC) can realize effective suppression of torque ripple. The decoupling relationship between open-phase control laws and fault-tolerant current is verified by simulation. The torque ripple of fault-tolerant and effect of torque compensation (TC) under all fault-tolerant conditions are simulated by finite element simulation. The stability of switching and correctness of torque compensation are verified by experiments.
