| Abstract: | Based on the biological robustness, an optimal control and optimization model is established for a class of continuous fermentation of glycerol to 1,3-propanediol. The existence of solutions of the optimal control is proved. A parallel particle swarm optimization （PSO） algorithm is developed, and the optimal feeding strategy of substrate is obtained through large-scale parallel computing. Numerical results show that the concentration of 1,3-propanediol at the steady-state moment can be increased considerably under the optimal feeding strategy. |
