Produktbeschreibung
Two main issues have been investigated: the combinational explosion, and the actual generation of the hardware controller. Most of the present approaches do not consider explicit communication between different components of a plant. We propose an incremental DCS technique which also applies to communicating systems. An initial modular abstraction is followed by a sequence of progressive refinements and computations of approximate control solutions. The last step of this sequence computes an exact controller. This technique is shown to have an improved time/memory efficiency with respect to the traditional global DCS approach. The hardware controller generation addresses the control non-determinism problem in a specific way. A partially closed-loop control architecture is proposed, in order to preserve the applicability of hierarchical design. A systematic technique is proposed and illustrated, for transforming the automatically generated control equation into a vector of controlfunctions. An application of the DCS technique to the correction of certain design errors in a real design is illustrated. To prove the efficiency, a number of examples have been studied.
