Aiming at a class of time varying delay nonlinear systems subjected to actuator fault, sensor fault and external disturbance, an improved unknown input observer is proposed. Concretely, first of all, an argument system is constructed and a descriptor system is designed. Then, a simultaneous state and fault estimation technique is developed. Furthermore,

An Open-Circuit Faults Diagnosis Method for MMC Based on Extreme Gradient Boosting
IEEE transactions on industrial electronics (1982. Print), 2023The diagnosis of open-circuit faults is required for the reliability of modular multilevel converters (MMC) and the complex operating environment of MMC may cause missing data and external noise in signal detections, where some of the present open ...

External short circuit fault diagnosis for lithium-ion batteries
2014 IEEE Transportation Electrification Conference and Expo (ITEC), 2014In this paper, a diagnostic method for identifying an external short circuit (ESC) fault for a lithium-ion battery is developed based upon active characterization experiments and online validation. The proposed method examines three criteria: voltage variation, current variation and temperature change rate.

Aiming at a class of nonlinear dynamic systems subjected to external disturbances and actuator faults, the sliding mode fault tolerant control is proposed. Firstly, a novel adaptive observer is proposed to estimate the state and fault signal simultaneously. Secondly, in accordance with the on line estimation information, the sliding mode fault tolerant

Generating external synchronizable test sequences that detect output-shifting faults
Proceedings of the 7th International Conference on Telecommunications, 2003. ConTEL 2003., 2003Synchronization problems arise when testing distributed systems. For some specifications, there is no synchronizable test sequence, and external synchronization operations between testers are unavoidable. Test sequences that involve external synchronization operations to solve synchronization problems are called external synchronizable test sequences ...
