Application of Linearization and Approximation

A drone flying through complex terrain often relies on more than one sensing method to estimate small changes in altitude. Along with direct measurements, air pressure provides a useful indirect indicator of vertical movement. Atmospheric pressure decreases as altitude increases, and this relationship is commonly described using an exponential model. Although accurate, converting pressure measurements into altitude values requires calculations that are too complex to perform repeatedly during...

Proposed a Mamba-enhanced multi-scale temporal network (Mamba-MSTN) integrating Multi-Scale Temporal Feature Extraction (MSTFE), Mamba for adaptive state perception, and Multi-Head Self-Attention (MHSA).

MSTFE module combines 1D-Residual Convolutional Neural Network (1D-RCNN) and Bidirectional Gated Recurrent Units (BiGRU) for multi-granularity temporal feature extraction.

Mamba module uses input-dependent state conversion for content-aware time-series modeling and key information filtering; MHSA enhances global dependency modeling.

Main Results:

The Mamba-MSTN framework demonstrated high sensitivity and robust generalization in binary and multi-class low-sample fault diagnosis tasks.
Achieved superior performance compared to mainstream methods in accuracy, processing efficiency, and resource consumption.
Effectively captured transient details and long-term trends, improving temporal characteristic extraction.

Conclusions:

The proposed multi-scale adaptive state-aware sequence learning framework significantly advances UAV fault diagnosis, particularly in data-scarce scenarios.
The Mamba-MSTN offers a promising solution for enhancing UAV reliability and operational safety in smart agriculture.
The method shows strong practical application potential due to its efficiency and accuracy.
