Webdeal with them. An FDI method is called robust if it can separate the effects of faults and uncertain factors on the residuals from each other. Robust FDI is classiﬁed into passive and active methods [1], [3]–[6]. In the active robust FDI approaches, a well-known technique is based on the unknown input observer (UIO) [3], [7]–[9].
