In order to implement the safe operation of batch reaction and to guarantee the quality of a desired product, the dynamic programming method is adopted to solve the optimization problem, and the common model control algorithm is employed to dynamically optimize and integratedly control the batch reaction process. In the investigation, first, the reaction process is divided into a dynamic optimization model and a process control one. Then, by considering the effects of uncertain parameters, the dynamic optimization and the close-loop control strategy are integrated to imporve the product quality and guarantee the operation safety. The proposed method is finally applied to a batch reactor adopting the consecutive exothermic reaction scheme. The results verify the feasibility and correctness of the method.
