The Twin Structure Model (TSM) is a coupled pair of structural models representing conservation and information processes, respectively. In the conservation structure the active elements correspond to the varions elementary physical and chemical changes, while the state of the system is modeled by the extensive quantities described by the passive elements. In the information structure, the active elements define the rules of the information processing, whilst the passive elements are places for the various signs. The connection between the conservation and information structures can be interpreted as transformations, determining the information sources and the intervention of the control. The Twin Structure Model is an optionally in parallel executable software tool for the dynamic simulation of controlled objects and for the control algorithm design.
