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 method of and system for processing a digital signal are disclosed. Disclosed also are an electric power system digital controlling system and a digital relay system which utilize the signal processing system for obtaining physical quantities of a voltage and a current inputted from the electric power system. An analog signal is sample-held. The sample-held data is converted into digital data which is then filtering-processed. Arithmetic processing is effected based on the data from a digital filter means. In this digital filter means, a blocking zone of the digital filter is set to a higher frequency zone than a passage zone of the analog signal. A sampling frequency is set so that a noise generating region is larger than the blocking zone. The synthesis noises are thereby caused in the blocking zone.

摘要： A self-tuning controller apparatus which com­prises: a control response pattern recognition portion (4) for receiving a set-point (SV) and a controlled variable (PV) of a process and for obtaining three performance indexes from a controlled variable response pattern generated in response to a change in the set-­point or a disturbance; a control parameter correction portion (6) for qualitatively evaluating the three performance indexes and for inferring a correction value of a PID control parameter on the basis of the result of evaluation; and a control performance dissatisfaction degree evaluation portion (7) for evaluating the inferred correction value of the PID control parameter in accordance with the dissatisfaction degrees of the two performance indexes for the respective target speci­fications of the two of the three performance indexes. The control performance dissatisfaction degree evalua­tion portion acts to make the PID control parameter converge stably. In a process control system including a plurality of vertically distributed control elements each capable of self-tuning its control parameter, the control performance dissatisfaction degree evaluation portion contributes to autonomous functioning of each of the control elements.
