摘要： A prediction control development device according to one aspect of the present invention generates a prediction model of a control amount by analyzing first time-series data of the control amount and provides the generated prediction model to a controller. The prediction control development device acquires second time-series data showing transition of a value of the control amount during prediction control using the prediction model, and evaluates prediction accuracy of the prediction model based on a difference between a prediction value by the prediction model and a value of the second time-series data. When the prediction accuracy of the prediction model is not allowable, the prediction control development device analyzes the second time-series data to newly generate a prediction model of the control amount, and provides the newly generated prediction model to the controller.

摘要： A technology for performing prediction control by which performance of a prediction model can be sufficiently exerted. A control system according to an aspect of the present invention 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.

摘要： A controller includes a control operation unit that cyclically performs a control operation for controlling a control target, a data generator that generates data showing a chronological change in a value associated with a control target, and an analyzer that analyzes data generated by the data generator and outputs an analysis result in a predetermined analysis target period. The analysis target period includes a plurality of sections. The data generator sequentially outputs section data showing a chronological change in a value for each of the plurality of sections included in the analysis target period. The analyzer analyzes the sequentially output section data for each section. When an analysis of section data for a section included in the analysis target period shows a predefined result, the analyzer eliminates an analysis of section data for one or more sections in the analysis target period that are subsequent to the section for which the analysis shows the predefined result.

摘要： The present invention reduces the probability of malfunction occurrence when performing predictive control of a device being controlled. In this control device of one aspect of the present invention, a prediction model for a control variable is used to calculate a prediction value from a measured value of the control variable, and a desired command value of the control variable is determined by correcting a desired basic value in accordance with the calculated prediction value. The degree of correction is determined on the basis of weight. The control device controls the operation of the device being controlled according to the determined desired command value. The control device assesses whether the device being controlled is operated appropriately on the basis of monitoring data relating to the operation result of the device being controlled, and optimizes the weight of the correction to make appropriate control possible based on the assessment result.

摘要： The disclosure provides an additional learning device, an additional learning method, and an additional learning program . The additional learning device includes: an acquisition unit (12) acquires information based on data observed in a control object which is controlled by an instruction in accordance with an output from a previously learned model outputting an objective variable with respect to an explanatory variable. A determination unit (14) determines whether or not the explanatory variable corresponding to the information acquired by the acquisition unit (12) exists as learning data of the model, that is, whether or not the explanatory variable is unknown. When the explanatory variable is determined to be unknown by the determination unit (14), an additional learning unit (16) acquires the objective variable corresponding to the unknown explanatory variable, correlates the unknown explanatory variable and the acquired objective variable, and additionally learns the model. The model is updated with regard to unknown disturbance events without requiring manpower.
