Abstract
In this work, the problem of detection and isolation of pitch actuator faults in wind turbines (WTs) is addressed. First, interval observers are used by means of the Luenberger observer to obtain an upper and a lower estimated bounds. The main advantage of this approach is that the new bounds enclose the real output measurement within a bounded interval in a guaranteed way under consideration of the uncertainties (in this case noise in the pitch measurement). Finally, residual signals are obtain...
