“…Then the resulting two-phase post fault currents will increase to 3 of the healthy phase current with phase angle shifted 60 о away from each other [11], [12]. This is illustrated by the phasor diagram in Figure 3 for an OPF in phase (a).…”

“…Methods with reconfiguration [11] are most applicable due to the fact that single-phase operation of the method without reconfiguration [9] even with modifications applied has the probability of matching the system mechanical resonance frequency at low speeds. One of the reconfiguration methods with extra inverter leg connected to the neutral point of PMSM is presented in [12], however still the main drawback of this method is the extra complexity of the power converter and additional cost and size. In [13] the authors employed a fourth leg in a manner that it replaces the faulty leg, yet the same drawback of extra complexity and additional cost and size remains the same.…”

This paper presents an integrated solution for a fault-tolerant three-phase permanent magnet synchronous motor (PMSM) field-oriented control drive subjected to an openphase fault (OPF) integrated with effective fault-tolerant detection methodology. The fault detection methodology is based on model predictive current control (MPCC), which is easy to apply, detect OPF in a range of microseconds, and robust under-speed or load transient. On the other hand, the fault-tolerant compensation is based on a neutral point connection together with stator current regulation to maintain the magneto-motive force (MMF)unchanged under open-phase failure. Controlling the motor phase currents in the post-fault condition ensures a rotating magnetic field similar to that produced during healthy conditions thus, reducing the saturation impact and ensuring the reliability of the control operation. The proposed integrated fault-tolerant drive is validated using MATLAB simulation that ensure the effectiveness of the proposed solution in steady state and during transients under different loading and rotor speed condition.

“…Permanent magnet synchronous motors (PMSMs) have been widely employed in servo control systems, such as in electrical vehicles, numerical control machines, and robotic fields, owing to its advantages of high power density, low electric power loss, and small structural size [1][2][3][4]. However, parameter mismatching, nonlinearity of the controlled model, and uncertain disturbances inevitably exist in the PMSM servo system, which decreases the tracking performance and stability [5].…”

This paper concentrates on a robust resonant control strategy of a permanent magnet synchronous motor (PMSM) for electric drivers with model uncertainties and external disturbances to improve the control performance of the current loop. Firstly, to reduce the torque ripple of PMSM, the resonant controller with fractional order (FO) calculus is introduced. Then, a robust two degrees-of-freedom (Robust-TDOF) control strategy was designed based on the modified resonant controller. Finally, by combining the two control methods, this study proposes an enhanced Robust-TDOF regulation method, named as the robust two degrees-of-freedom resonant controller (Robust-TDOFR), to guarantee the robustness of model uncertainty and to further improve the performance with minimized periodic torque ripples. Meanwhile, a tuning method was constructed followed by stability and robust stability analysis. Furthermore, the proposed Robust-TDOFR control method was applied in the current loop of a PMSM to suppress the periodic current harmonics caused by non-ideal factors of inverter and current measurement errors. Finally, simulations and experiments were performed to validate our control strategy. The simulation and experimental results showed that the THDs (total harmonic distortion) of phase current decreased to a level of 0.69% and 5.79% in the two testing environments.

“…Modified transformations are known also in post-fault operation of multiphase machines [17] or even in three-phase machines fed from four-wire power converters [18] in which new reference frames can be calculated offline for each phase fault and mapped in a table, due to the fixed position of stator phase windings. For a grid connected converter, estimation of new transformation parameters has to be done online, because during a voltage dip, phase displacement and voltage drop depend on the type and depth of grid voltage dip.…”

The paper deals with a new nonlinear transformation providing representation of unbalanced threephase signals (voltage and currents) as vectors which have constant components in a new rotating frame. Using the proposed transformations the control system of a power electronic converter operating with an unbalanced grid can be equipped with proportional-integral PI controllers, without the use of resonant terms, for which anti-wind-up structures are more complicated and non-intuitive. The paper presents derivation of new direct and inverse transformations, features, a power converter model in a new frame, simulation results showing the waveforms of signals transformed to the new non-Cartesian frame, and simulation and experimental results of voltage oriented control for a grid connected power converter.
