Fault Diagnosis and Fault-Tolerant Control of Wind Turbines via sliding mode control

Abstract

The proposed method describes adaptive fault estimation algorithm smc is proposed to enhance the rapidity and accuracy performance of fault estimation. In particular, an electrical fault scenario, the DFTG winding short circuit fault, is considered due to its high occurrence rates. Based on the fault estimation information, a fault compensator is designed based on fault information provided by the fault diagnosis scheme to guarantee the stability of the system. This adaptive fault estimation algorithm is proposed to enhance the rapidity and accuracy performance of fault estimation. In particular, an electrical fault scenario, the DFTG winding short circuit fault, is considered due to its high occurrence rates. Based on the fault estimation information, a fault compensator is designed based on fault information provided by the fault diagnosis scheme to guarantee the stability of the system, and it incorporates with a traditional controller to provide an online fault compensation of winding short circuit faults.
