Patent number: 11892819Abstract: An objective of the present invention is to provide a control device, control system, control method, and computer-readable storage medium, for enabling verification of the reliability of operation machine control. Provided is a control device comprising: a control part comprising a controller for outputting output data with regard to input data, said control part serving to control an operation machine using the controller; an acquisition part for acquiring attribute information including statistics of previously obtained input data and output data; and an evaluation part for, on the basis of a comparison of the attribute information with new input data being newly inputted into the controller and/or new output data being newly outputted from the controller with regard to the new input data, evaluating to what extent the new input data and/or the new output data deviate from the statistics.Type: GrantFiled: February 21, 2019Date of Patent: February 6, 2024Assignee: OMRON CorporationInventors: Yuki Ueyama, Takashi Fujii, Yasuaki Abe, Kazuhiko Imatake, Nobuyuki Sakatani

Patent number: 11762347Abstract: A control device executes a step of starting a computation processing of a prediction model; a step of computing a remaining processing time until the computation processing is completed after starting the computation processing of the prediction model; a step of determining whether the determination of the command value based on an output obtained from the prediction model is made within a control timing for controlling the operation of manufacturing by the manufacturing device, on the basis of a computed remaining processing time; and a step of stopping, when it is determined that the determination of the command value is not made within the control timing, the computation processing of the prediction model, determining the command value on the basis of a value of an intermediate result of the computation processing, and controlling the operation of the manufacturing device on the basis of the determined command value.Type: GrantFiled: March 13, 2019Date of Patent: September 19, 2023Assignee: OMRON CorporationInventors: Yuki Ueyama, Yasuaki Abe, Nobuyuki Sakatani, Kazuhiko Imatake, Takashi Fujii

Patent number: 11681261Abstract: 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.Type: GrantFiled: March 13, 2019Date of Patent: June 20, 2023Assignee: OMRON CorporationInventors: Yasuaki Abe, Yuki Ueyama, Takashi Fujii, Kazuhiko Imatake

Patent number: 11480931Abstract: This learning device provides a learned model to an adjuster containing a learned model learned to output a predetermined compensation amount to a controller, in a control system including the controller outputting a command value obtained by compensating a target value based on a compensation amount and a control object controlled to process an object to be processed. The learning device includes: an evaluation part obtaining operation data including the target value, command value and control variable and evaluates the quality of the control variable; a learning part generating candidate compensation amounts based on the operation data, and learning, as teacher data, the generated candidate compensation amount and the specific parameter of the object, and generating a learned model; and a setting part providing the learned model to the adjuster if the evaluated quality is within an allowable range.Type: GrantFiled: March 8, 2019Date of Patent: October 25, 2022Assignee: OMRON CorporationInventors: Takashi Fujii, Yuki Ueyama, Yasuaki Abe, Nobuyuki Sakatani, Kazuhiko Imatake
