The viability and effectiveness of the proposed PMSM sensorless field-oriented control system has been verified by MATLAB/Simulink platform. The proposed adaptive CCF and PLL technique allows to provide the effective chattering suppression, robustness, desired estimation error of rotor position angle with fast convergence rate and can be adopted in the high-performance sensorless PMSM drives.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

This has prompted the research community to explore aviation safety using advanced machine learning algorithms and data analysis techniques. To address the safety concerns in aviation, a novel ensemble classification model has been proposed, leveraging the Aviation Safety Reporting System (ASRS) data. The focus of this model is to analyze and assess the safety aspects pertaining to individuals affected within the aviation system. The ensemble classification model shall contain two modules: the data-driven module consisting of data cleaning, feature selection, and imbalanced data division and reorganization, and the modeldriven module stacked by Random Forest (RF), XGBoost (XGB), and Light Gradient Boosting Machine (LGBM) separately. The results indicate that the ensemble model could solve the data imbalance while vastly improving accuracy. LGBM illustrates higher accuracy and faster run in the analysis of a single model of the ASRS-based imbalanced data, while the ensemble model has the best performance in classification at the same time. The ensemble model proposed for imbalanced data classification can provide a certain reference for similar data processing while improving the safety of civil aviation.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.
