Abstract:
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.
