CONTROL PARAMETER ADJUSTMENT DEVICE
First Claim
1. A control parameter adjustment device comprising:
- a command-value generation unit that generates a position command;
a servo control unit that calculates a drive command such that a response position of a driven object follows the position command;
a correction model unit that generates, by using a model expressed by two or more types of parameters, a correction command for correcting a response error that is a difference between the position command and the response position; and
a parameter search unit that corrects the model by using a combination of values of the parameters by which the response error is minimized, the combination of values of the parameters being from among a plurality of combinations of values of the parameters, whereinthe control parameter adjustment device drives the driven object in accordance with the drive command and the correction command.

Abstract
A control parameter adjustment device includes a command-value generation unit that generates a position command; a servo control unit that calculates a drive command such that a response position of a driven object follows the position command; a correction model unit that generates a correction command for correcting a response error that is a difference between the position command and the response position by using a model expressed by two or more types of parameters; and a parameter search unit that corrects the model by using a combination of values of the parameters, by which the response error is minimized, among a plurality of combinations of values of the parameters. The control parameter adjustment device drives the driven object on the basis of the drive command and the correction command.
