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