Robust Time-Delay Optimal Control of 1,3-Propylene Batch Fermentation

Based on the established nonlinear time-delay dynamical system, a time-delay optimal control model with continuous state inequality constraints is established, taking the maximum yield of 1, 3-propylene glycol at terminal time as the performance index under the premise of determining the optimal parameters. The numerical results showed that the yield of 1, 3-propylene glycol was obviously increased at the terminal time.
