A control device for controlling a controlled apparatus, and a control method therefor. |
摘要 |
<p>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). <IMAGE></p> |
