Abstract

A control system for the tubular reactor-unit has been synthesized, which is a combination of feedforward, feedback and inferential control configurations. The reactor chosen is fast; transient period for a given disturbance varies between 20 and 100 sec, as found from numerical simulation. Therefore a fast on-line control scheme using heuristic approach has been used in which disturbances, manipulated variables and control variables are correlated based on the steady state model of the reactor. Testing of the control scheme has been conducted for both instantaneous as well as delayed control action by numerical simulation
