✦ Synopsis

This paper presents a methodology of dynamic optimization and optimal control of a batch electrochemical reactor where a series of two reactions A & B & D takes place. The optimization problem is stated as to determine the optimal pro"les of the electrode potential which maximize the selectivity of product B, in a given batch period and under speci"ed constraints. The main important steps which are worth to be analyzed prior to any on-line implementation are presented and discussed. Thus, after the formulation of the optimization problem, di!erent dynamic optimization methods have been used for the determination of optimal time-varying pro"les of electrode potential. These pro"les were then compared to the best uniform operations through the relative improvements of the performance index. The sensitivity analysis of the optimization criterion and control variables to the model parameters was carried out before state observation and implementation of optimal control pro"les. 1999 Elsevier Science Ltd.
