A hybrid method of differential evolution with application tooptimal control problems of a bioprocess system

摘要

A hybrid method of differential evolution is developed in thisstudy. Two additional operations (accelerated phase and migrating phase)are embedded into the original version of differential evolution. Thesetwo phases are used for improving the convergence speed without reducingthe diversity among the individuals. The method of multiplier updating,incorporated in the proposed method, is introduced to solve theconstrained optimization problems. The method is then extended to solvethe simultaneous optimal control and optimal parameter selectionproblems of a bioprocess system
