“…From this description, it could be noted that this method resembles a flux-based model reference adaptive system (MRAS) [518], which will be further discussed later in Section 7.3.1.7. Nevertheless, in this case is substantially more elaborate [203] than in existing MRASs for this purpose. In fact, this novel observer, called robust simplified dynamic observer, is proved in [203] to yield better speed accuracy than state-of-the-art MRAS speed estimators.…”

Multiphase drives offer enhanced fault-tolerant capabilities compared with conventional three-phase ones. Their phase redundancy makes them able to continue running in the event of faults (e.g., open/short-circuits) in certain phases. Moreover, their greater number of degrees of freedom permits improving diagnosis and performance, not only under faults affecting individual phases, but also under those affecting the machine/drive as a whole. That is the case of failures in the dc link, resolver/encoder, control unit, cooling system, etc. Accordingly, multiphase drives are becoming remarkable contenders for applications where high reliability is required, such as electric vehicles and standalone/off-shore generation. Actually, the literature on the subject has grown exponentially in recent years. Various review papers have been published, but none of them currently cover the state-of-the-art in a comprehensive and up-to-date fashion. This two-part paper presents an overview concerning fault tolerance in multiphase drives. Hundreds of citations are classified and critically discussed. Although the emphasis is put on fault tolerance, fault detection/diagnosis is also considered to some extent, because of its importance in fault-tolerant drives. The most important recent advances, emerging trends and open challenges are also identified. Part 1 provides a comprehensive survey considering numerous kinds of faults, whereas Part 2 is focused on phase/switch open-circuit failures.

“…This is a good example showing the spirit of the IFO nature of sensorless induction motors, that an accurate estimate of flux/emf is not needed, because the IFO d-axis angle estimate only depends on the speed estimate. However, there are also attempts to compensate the gain and lag introduced in ( 14) [144].…”

“…13 The pioneer work on MRAS in [96] (and also the followup work [129], [158]) is a good example showing the spirit of IFO-PE that an accurate estimate of flux/emf is not needed, by using (28) as the reference model and using high-pass filtered i for current model as the adjustable model. There are also attempts to compensate for the gain and lag introduced in (28) (see, e.g., [159]). The convergence of MRAS based flux estimate needs an analysis of the error dynamics of the flux error and the mismatch between VM and current model [160].…”

This paper reviews sensorless algorithms for both induction motors and permanent magnet motors using the active flux model, such that any design applicable for non-salient pole ac motors can also be included in the review framework. The proposed review framework classifies all sensorless algorithms following a five-layer hierarchy abbreviated as O-I-M-A-I, resulting in four main categories as i) inherently sensorless position estimation, ii) non-inherently sensorless position estimation, iii) post-position-estimation speed estimation, and iv) speed estimation for indirect field orientation. Various ac motor models are derived by assuming a constant active flux amplitude, based on which seven generic sensorless algorithms are summarized in a tutorial. Recommendations are made for sensorless drive designers to begin with inherently sensorless method such that the two-way coupling between position estimation and speed estimation is avoided. Finally, classical induction motor model results from time-varying active flux amplitude and slip relation, for which a state transformation is recommended for achieving global stability.<br>
