Genetic Algorithms vs. Knowledge-Based Control of PHB Production

摘要

The paper proposes an approach using Genetic Algorithm (GA) fordevelopment of optimal time profiles of key control variable of Poly-HydroxyButyrate(PHB) production process. Previous work on modeling and simulation of PHBprocess showed that it is a highly nonlinear process that needs special controllersbased on human experience, as such fuzzy logic controller proved to be a goodchoice. Fuzzy controllers are not totally replaced, due to the specific processknowledge that they contain. The achieved results are compared with previouslyproposed knowledge-based approach to the same optimal control task.
