Abstract
Abstract A phosphoric acid production plant and its controls have been studied. New controls and monitoring systems which are partly realized with fuzzy logic, have been installed. Sulphuric acid concentrations in two reactors are controlled with fuzzy logic modules. The fuzzy logic concentration control is compared with traditional PID-control and Internal Model Control. Some modelling work that has been necessary in order to be able to design the IMC-system is presented. A performance index for phosphoric acid filtration unit has been introduced and it is one of the variables that are used to control the amount of raw material feed. Two fuzzy logic modules are used for this purpose. The first one develops the performance index and the other one the proposals for the new raw material feed.
