“…3.4.1.6. Current d 1 -q 1 PI and x-y Stationary PI Control Using Full-Order VSD A less common option under phase OC faults is to control the x-y current by PI regulation in stationary frame, while using the complete VSD and controlling the current of the main plane by conventional d 1 -q 1 PI control [15,147,162,225]. As in some other aforementioned schemes, the ac disturbances/references are not rejected/followed with zero steady-state error in this manner, but control complexity is avoided.…”

Multiphase machines are very convenient for applications that require high reliability. In this two-part survey, the state of the art about fault tolerance in multiphase drives is reviewed. In Part 1, an overview including numerous fault types was presented, along with fundamental notions about multiphase drives. Here, in Part 2, the focus is placed on phase/switch open-circuit (OC) faults in particular, which have received the most attention in the literature. Phase OC failures involve OCs in stator phases or in converter-machine connections, and switch/diode OCs are frequently dealt with similarly or identically. Thanks to the phase redundancy of multiphase drives, their operation can be satisfactorily continued under a certain number of OCs. Nonetheless, the procedure to follow for this purpose is far from unique. For given OC fault conditions, numerous fault-tolerant possibilities can be found in the literature, each of them with different advantages and disadvantages. Moreover, a great variety of methods have also been devised to detect and diagnose phase/switch OC failures so that, as soon as possible, the most appropriate fault-tolerance measures are applied. Thus, given the broad literature about tolerance to phase/switch OC faults in multiphase drives, the survey presented here is expected to be of great interest for the research community and industry.

This paper proposes a novel control approach for fault-tolerant control of dual three-phase permanent magnet synchronous motor (PMSM) under one-phase open-circuit fault. A modified six-phase static coordinate transformation matrix and an extended rotating coordinate transformation matrix are investigated considering the influence of the fifth harmonic space on fault-tolerant control. These mathematical models are further analyzed in the fundamental space and the fifth harmonic space after the fault and to eliminate the coupling between the d-q axis voltage equation in the fundamental wave space and the d-q axis voltage equation in the fifth harmonic space, a secondary rotation coordinate transformation matrix is proposed. To achieve the purpose of reducing torque ripple, the fault-tolerant control method proposed in this paper not only takes the minimum copper loss as the constraint condition, but also injects the fifth harmonic current. The experimental result of current and torque is used to verify the accuracy of fault-tolerant control.

“…The resonant controller is another choice for the current control under FT conditions because it has the perfect ability to track ac signals [14]. Many controllers based on the resonant controller, such as proportional resonant (PR) controller and proportional-integral resonant (PIR) controller, are applied in the current control under FT conditions [15][16][17][18]. They both can be applied in static frames or rotating reference frames.…”

To achieve the fault-tolerant operation of motor drives, many control algorithms have been proposed. Among them, it is more flexible and intuitive to find solutions to phase current at phase coordinate. Then it is necessary to track the given phase current. Up to now, several current controllers have been proposed. A hysteresis controller suffers from the drawback of the variable switching frequency. Proportional-integral control cannot track ac signals with zero error. As to the proportional resonant controller, its performance is highly dependent on the accuracy of motor speed detection. Considering this, a current controller is based on the adaptive filter. The adaptive filer is worked as the current controller by adjusting its structure, in which the motor model is extra introduced. The controller updates the tap weight in each control cycle until it outputs the optimal voltage to track the given phase current. Besides, the adaptive algorithm is improved by adding a feedforward term to gain a higher dynamic response. Moreover, to ensure the stability of the controller, the control parameter selection principles are analysed and acquired accordingly. Finally, several groups of experiments are conducted. The experiment results coincide with the analysis.
