Abstract

Accurate identification of magnet flux linkage is of great importance for the condition monitoring and control optimization of permanent magnet synchronous motor (PMSM) drives. In this work, a normal-operation-undisturbed magnet flux linkage monitoring technique using a mechanical-model-based dual time-scale approach is presented. The proposed technique is composed of two Adaline-type asymptotic observers, which operate at different time scales and provide updates to each other to guarantee accuracy and cope with rank deficiency during the identification. With the aid of Lyapunov theory, a dynamic learning factor is ingeniously designed for each of the two Adaline-type asymptotic observers, which yields powerful noise immunity and helps to guarantee observer stability. In comparison to existing magnet flux linkage identification solutions, the proposed method is impervious to inverter nonlinearity and magnetic saturation, and meanwhile, it circumvents the need for harmonic signal injection and control structure alteration so as to eliminate the resulting possibility of affecting normal motor operations. Simulations, along with real-time experiments under different temperatures, loads, and speeds, are presented to demonstrate the feasibility of the proposed technique and its capability to accurately monitor the magnet flux linkage.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Excessively high voltage stress increases the risk of device failure and necessitates higher-rated, larger, and more expensive components, compromising system compactness and cost-effectiveness.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
