The problem of synthesis of process control structures for a chemical plant is formulated. The multilayer decomposition approach is used to classify disturbances in order to decompose control tasks into regulatory and optimizing control. The chemical plant is decomposed along the multiechelon concept to provide subsystmes for which optimizing and regulatory control structures are developed. Feedback optimizing control structures are introduced along with their attractiveness in translation of economic objectives into process variables. The result is an algorithm to generate alternative control structures, mainly based on simple structural models.
