Embodiment Construction
[0036] The method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific examples of implementation.
[0037] Such as figure 1 As shown, the present invention discloses a chemical fault monitoring method based on a generalized multi-block independent element analysis model. The following combines a specific industrial process example to illustrate the specific implementation process of the inventive method and its advantages over the existing methods .
[0038] The application object is from Tennessee-Eastman (TE) chemical process experiment, and the prototype is an actual process flow of Eastman chemical production workshop. Currently, the TE process has been widely used in fault detection research as a standard experimental platform due to its complexity. The whole TE process includes 22 measured variables, 12 manipulated variables, and 19 component measured variables. The TE process object can simulate a vari...
