The invention relates to a process and circuit for improving the dynamics of regulating circuits or measuring paths. The items concerned by the invention are any regulating circuits and measuring paths, e.g. in the chemical industry. According to the invention, the regulation discrepancy is measured m times at the beginning of each cycle at equal distances, where m is a precision-dependent constant, the difference is found between these measured values of the regulation discrepancy and the corresponding regulation discrepancies provided by a model, characteristic parameters used to update the model are found by means of these differences r, an extrapolation of the regulation discrepancy is made with the aid of the updated model and the rise in the extrapolated regulation discrepancy is also determined with the aid of the updated model, and then the linear function obtained from the magnitude and rise of the extrapolated regulation discrepancy or the measurement signal for the next cycle or its value (ordinate) for the time of the start of the cycle is determined and, using this and the value of the function determined likewise at the beginning of the previous cycle, a new linear function is formed, the variation of which between the two values (ordinates) is used as a regulation discrepancy (reconstructed signal regulation discrepancy) and fed into the regulating circuit as an auxiliary value or used as an actual measurement. |
