Perspectives on process monitoring of industrial systems

Process monitoring systems are necessary for ensuring the long-term reliability of the operation of industrial systems. This article provides some perspectives on progress in the design of process monitoring systems over the last twenty years. Methods for each step of the process monitoring loop are summarized. The challenges in the field and opportunities for future research are discussed. When looking into the future, it is argued that advances are likely to come from combining different methods to exploit the strengths of various techniques while minimizing their weaknesses.
