TEST CONTROL DEVICE, TEST SYSTEM, AND CONTROL METHOD

A test control device includes a test variable generation device and a test processing device. The test variable generation device uses a test prediction model to generate a first manipulated variable based on a difference between a target value and a first controlled variable value from a device under test. The test processing device acquires a second controlled variable value from the device under based on use of the first manipulated variable value. The test variable generation device notifies the device under test of end of a test if the second controlled variable value is equal to or greater than the target value or uses the test prediction model to generate a second manipulated variable based on a difference between the target value and the second controlled variable value when the second controlled variable value is less than the target value.
