Fault Detection in CSTR using MATLAB.

The paper discusses the diagnosis of different faults taking place in a continuous stirred tank reactor (CSTR). The reaction taking place is the alkaline hydrolysis of ethyl acetate in the presence of sodium hydroxide. The objective of the paper is to detect the faults occurring in the CSTR and to determine their magnitude and time of occurrence. The fault finding strategy is two pronged- analyzing the faults based on their deviation from the normal behaviour and estimating their time of occurrence from the plots. The next step undertaken is the evaluation of the fault deviation in percentage and subsequently certain conclusions are drawn from these.
