In this article, a position sensorless control strategy for the five-phase interior permanent magnet synchronous motor (IPMSM) by injecting pseudo-random signal into the third harmonic space is proposed. The conventional sensorless control of five-phase IPMSM based on third harmonic space extracts rotor position information by injecting high-frequency square voltage signals into the third harmonic space. However, high-frequency square-wave voltage injection (HFSVI) produces a loud audible noise. Different from the conventional HFSVI strategy, the proposed strategy injects simplified pseudo-random fixedfrequency phase-switching (SPRFFPS) signal into the third harmonic space of the five-phase IPMSM to reduce high-frequency audible noise. To verify the effectiveness of the proposed strategy, the power spectral density (PSD) of phase current is analyzed. Also, since high-frequency signal is not injected into the fundamental space, the digital filter in the fundamental space current loop will no longer be needed, which avoids time delay and degradation of control performance. Finally, the correctness of the proposed strategy is verified by experiments.

“…In contrast to conventional three-phase motors, five-phase motors have the property of multiple harmonic spaces. Among these multiple harmonic spaces, the third harmonic space is more often used for fault tolerant control, sensorless control, etc [10]- [13].…”

“…Such solutions are often applied to frequency converters [5] and, in some situations, to multiphase motors [6], in which the loss of one phase has a smaller impact on the operation of the system than in the case of three-phase motors. In the case of CS faults in drive systems, current measurement is often used in three phases, so that in the event of a failure of one of the CSs, the third one is used as redundant and, based on two measurements, the missing signal in the third phase is determined [7].…”

Vector controlled drives require stator current information for use in current feedback and/or state variable estimators. That is why the detection and compensation of possible CS damage is so important. This article focuses on current sensor (CS) fault-tolerant control (FTC) in induction motor (IM) drive systems. In contrast to solutions known from the literature, two Modified Luenberger Observers (MLO) were applied, allowing for high-quality estimation of currents used in the detector and fault compensator. In a simple implementation of a detection algorithm based on residuals, an adaptive threshold coefficient was employed, enabling effective detection of various types of faults, regardless of whether the second current sensor was faulty or intact. The presented solution was evaluated during both motor and regenerative operation, with faults occurring in transient states, unlike solutions known in the literature.
