A fault diagnosis method for pilot-operated solenoid valves based on CRQA-Stacking integrated learning
A fault diagnosis model for pilot-operated solenoid valves based on cross-recurrence quantification analysis (CRQA) and stacking heterogeneous ensemble learning is proposed, achieving high accuracy and stability in fault diagnosis for sparse and imbalanced fault samples.
