Control device, control system, control method, and computer-readable storage medium

A control system, comprising a learning device that is configured to execute learning processing of a controller by machine learning in which learning data defining a relationship between input data and output data is used, and a control device having a control part that is configured to use the controller to control an operation machine,

• wherein the learning device further comprises
• a generation part that is configured to generate attribute information comprising statistics of the previously obtained input data and output data;
• and
• the control device further comprises:
• an acquisition part that is configured to acquire the attribute information, and
• an evaluation part that is configured to evaluate, based on comparison of the attribute information with at least one of new input data newly input to the controller and new output data output from the controller with respect to the new input data, to what extent at least one of the new input data and the new output data deviates from the statistics.

A control method, comprising:

• using a controller for outputting output data with respect to input data to control an operation machine;
• acquiring attribute information comprising statistics of the input data and the output data;
• and
• evaluating, based on comparison of the attribute information with at least one of new input data newly input to the controller and new output data output from the controller with respect to the new input data, to what extent at least one of the new input data and the new output data deviates from the statistics.

A non-transitory computer-readable storage medium, which stores a control program,

• causing a calculation part equipped in a control device to operate as:
• a control part that comprises a controller for outputting output data with respect to input data and uses the controller to control an operation machine;
• an acquisition part that acquires attribute information comprising statistics of the input data and the output data;
• and
• an evaluation part that evaluates, based on comparison of the attribute information with at least one of new input data newly input to the controller and new output data output from the controller with respect to the new input data, to what extent at least one of the new input data and the new output data deviates from the statistics.
