Robust Model- Based Fault Detection and Isolation for V47/660kW Wind Turbine

In this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for V47/660kW wind turbine operated in Manjil wind farm, Gilan province, Iran. According to the acquired data from Iran wind turbine industry, common faults of the wind turbine such as sensor fault...

P Arametric Identification for Robust Fault Detection

The w orkpresents some simulation results concerning the application of robust model{based fault diagnosis to an industrial process by using iden ti cation and disturbance de{coupling techniques. The rst step of the considered approach iden ti es sev eral equation error models b y means of the input{output data acquired from the monitored system. Each model describes the di erent w orkingcondit...

Dynamic Threshold Generators for Robust Fault Detection

Detection of faults, such as clogged valves, broken bearings or biased sensors, has beenbrought more and more into focus during the last few decades. There are two mainreasons why faults are important to detect at an early stage. Firstly, faults in safetycritical applications, such as aircraft, nuclear reactors, cars and trains, may create risks ofpersonal injuries. Secondly, fa...

Robust Subspace Based Fault Detection

Subspace methods enjoy some popularity, especially in mechanical engineering, where large model orders have to be considered. In the context of detecting changes in the structural properties and the modal parameters linked to them, some subspace based fault detection residual has been recently proposed and applied successfully. However, most works assume that the unmeasured ambient excitation l...
