This paper presents the development of a bilinear system model and the application of a bilinear fault detection observer to a papermaking machine to detect various simulated faults. First a suitable MIMO bilinear model representation of the wet end section of the process is found. Then, a set of robust bilinear fault detection observer is used to generate the residuals which are robust to disturbance but sensitive the faults. A series of test is carried out by simulating four actuator and four sensor faults, which are successfully detected and isolated by using this method.
