ARTIFICIAL RAINDROPALGORITHM BASED CONTROL FOR FAULT TOLERANCE AND RECONFIGURATION OF DISTILLATION COLUMN
GANESH RM Dr. S. MANOHARAN
In this paper, a novel nature-based meta-heuristic
method, named artificial raindrop algorithm is proposed.
This algorithm is stimulated from the phenomenon of natural
rainfall and applied for nonlinear distillation column using
parallel cascade control. Distillation column is an important
process in chemical engineering. Distillation is a technique
of separating mixtureswith given contrasts in volatilities of
components in a boiling fluid mixture. Cascade control
scheme is efficient for systems that have large time constants
and disturbances. It provides fast recovery from
disturbances. Among the two methods of cascade such as
series and parallel cascade, later reduces steady state error
compared to series cascade.In this paper, various controllers
such as PID and fuzzy gain scheduling PID controller are
analyzed for flow control with fault tolerance in distillation
column. Proposed artificial raindrop algorithm based results are compared with the PID and fuzzy gain scheduling PID controller based control to validate the enhanced performance of the proposed system. Entire system is analysed using Matlab/Simulink.
