PA-OMT: A performance assessment and online monitoring toolbox for process monitoring and fault detection

Process monitoring and fault detection (PM-FD) methods have been widely used in practice to ensure the safe operation of the process. It has been found that although lots of PM-FD methods were proposed, there is few work focusing on developing a versatile performance assessment software to determine the optimal method for on-line monitoring. This paper is devoted to develop a MATLAB-based performance assessment and on-line monitoring toolbox (PA-OMT) for process monitoring. The software has a friendly graphical user interface (GUI), and is packaged into a separate version. It can be installed in different versions of Windows system and used without MATLAB. The purpose of the toolbox is to integrate performance assessment and on-line monitoring, and to provide a general platform for the application of PM-FD methods. Nine important basic algorithms are collected inside the toolbox, and external algorithms can also be uploaded through the interface. The platform is applied to the Tennessee Eastman (TE) process, which proves the effectiveness, versatility and practicability of the toolbox.
