Classification of dynamic models of control objects of chemical technological processes

The classification of dynamic models of objects of control in the chemical-technological industry worked out on the basis of dynamic and economic indices is considered. The classification structures are constructed on the hierarchical principle from simplest dynamic elements (integrating, transport) and non-dynamic elements (a hysteresis element, a summator, an amplifier, a multiplier, a detector). The relations and the mutual structural conversions of the classified models are shown. The classification table for the models with concentrated parameters is given. Certain nonlinearities of the object are taken into account in the structures of models. Examples with the objects modelled by the structures considered are given.
