Abstract
A control system includes a storage that stores a computational model of a reference response profile representing a frequency characteristic of a reference state of a control target corresponding to a first command, and circuitry configured to calculate a first actual response profile representing a frequency characteristic of an actual state of the control target having responded to the first command. The circuitry is further configured to acquire an error between the reference response profile and the first actual response profile, and cause a controller to output, to the control target, a second command that is based on a frequency at which the error is greater than a threshold. Additionally, the circuitry is configured to calculate a second actual response profile representing a frequency characteristic of an actual state of the control target having responded to the second command, and update the computational model based on the second actual response profile and the reference response profile.
