摘要:
In order to control an apparatus (1), such as a rolling mill, a control device (4) may use a pre-set operation pattern to generate a pre-set command signal, which is then modified. That first modification may be part of a feedback loop (Fig. 33) in dependence on the variation of a variable operation device (2) of the apparatus (1), on a plurality of pre-set signals may be combined by fuzzy logic (Fig. 29). Then the relationship between the modified pre-set command signal and the variation of the variable operation device (2) is investigated to generate a compensation signal which is used to modify further the pre-set command signal. In a feedback loop (Fig. 33), that further modification may compensate for changes in the operating point of the loop, due to changes in the apparatus (1) being controlled. In a fuzzy logic arrangement (Fig. 29), the compensation signal may be a further control pattern developed by the control device (4) itself, which is combined with the pre-set patterns by fuzzy logic. The control device may be in the form of a series of modules (375, 379).

摘要:
A data transmission system for transferring data between a plurality of processors (200A - 200G, 200Z, 2000) and between the processors and an input/output unit (303) through a common bus (301) has linkage units (300A - 300G, 300Z, 300L) between the processors and the bus and an address controller (302) to manage the bus. Each of the linkage units has a two-port random access memory (42A - 42G) for storing data necessary for the processor. The processor processes the data stored in the memory and writes a result of the processing in an output area of the memory. The processing of the processors and the data transfer through the bus are essentially separated and carried out independently.
