  • Patent number: 11681261
    Abstract: A control system estimates a numerical value range within which a command value can fall from a distribution of second data relating to the command value in a learning data set used to construct a prediction model, and in such a manner that a first acceptable range prescribed by a preset first threshold value with respect to a command value for a subject device is extended, decides a second threshold value with respect to the command value for the subject device on the basis of the estimated numerical value range. Further, in an operational phase, on the basis of an output value from the prediction model, the control system decides a command value for the subject device within a second acceptable range prescribed by the decided second threshold value, and controls an operation of the subject device on the basis of the decided command value.

  • Publication number: 20230173573
    Abstract: Accuracy of feedforward control for a wire straightener is improved. A feedback operation amount to a straightener is determined by a feedback control means based on an error between a target curvature and a straightening curvature. A feedforward compensation means determines a feedforward compensation value from a measurement value of the straightener using a prediction model. A learning means performs machine learning on the prediction model using teaching data. The learning means adds at least one combination including the measurement value and a manipulated variable when an absolute value of an error is smaller than a reference value to the teaching data.
