摘要

Abstract

With the Industry 4.0 era coming

modern chemical plants will be gradually transformed into smart factories

which sets higher requirements for fault detection and diagnosis (FDD) to enhance operation safety intelligence. In a typical chemical process

there are hundreds of process variables. Feature selection is a key to the efficiency and effectiveness of FDD. Even though artificial immune system has advantages in adaptation and independency on a large number of fault samples

antibody library construction used to be based on experience. It is not only time consuming

but also lack of scientific foundation in fault feature selection

which may deteriorate the FDD performance of the AIS. In this paper

a fault antibody feature selection optimization (FAFSO) algorithm is proposed based on genetic algorithm to optimize the fault antibody features and the antibody libraries' thresholds simultaneously. The performance of the proposed FAFSO algorithms is illustrated through the Tennessee Eastman benchmark problem.
