Detecting and isolating sensor and actuator faults in solution copolymerization of MMA and VAc process

In this work, we consider the problem of isolating actuator and sensor faults in the solution copolymerization of Methyl Methacrylate (MMA) and Vinyl Acetate (VAc) monomers. To this end, first a bank of high gain observers are designed. Subsequently, fault detection and isolation (FDI) filters are designed for the copolymerization process. The proposed nonlinear FDI filters are applied to the copolymerization process.
