Fault Detection and Diagnosis in Distillation Tower of the Tennessee-Eastman Model using Hotelling's T-squared Method %K Tennessee-Eastman Process %K fault detection %K distillation tower %K Hotelling's T-squared %R %X Control of the distillation tower is one of the main concerns in the design of chemical processes due to its high importance. Operational errors may occur in distillation towers for various reasons, leading to serious disruptions in process performance or the occurrence of undesirable incidents. In this research, an attempt has been made to use one of the existing validated models for the Tennessee-Eastman Process distillation tower in the MATLAB software to identify potential malfunctions in the tower's operation related to this process. Hotelling's T-squared test is employed for error detection. After detecting errors using the proposed diagnostic method, the type of fault can be determined. The presented method can accurately detect potential model errors within a short period (up to 0.1 hour). %U https://www.nsmsi.ir/article_697974_18ecfd44e9f685eecc237f387cdb5162.pdf
