The purpose of this paper is to describe the implementation of a hierarchical distributed control system for a chemical pilot plant using industrial standard components. The control system consists of three components: regulatory control (mainly PID controllers), multivariable control (Dynamic Matrix Control controller) and the optimization and economic layer (Linear Programming). This work also includes details of the implementation tools: PROFIBUS, LabVIEW and data acquisition modules. The paper concludes with two possible solutions that deal with plants with integral behaviour.
