Abstract
To efficiently adjust a control parameter of a servo control device. The parameter adjustment method includes the following procedure. That is, acquiring sensor data that is time-series data of a position deviation that is a difference between a target position and an actual position of a driver and is detected using a sensor. Correcting the sensor data based on a position deviation detected using the sensor after a timing at which movement of the driver based on a position command for moving the driver to the target position has ended. Calculating a settling time from a timing at which the driver is located at the target position in the position command to a timing at which the driver reaches an allowable position. Predicting a control parameter such that the settling time calculated based on the corrected sensor data satisfies a predetermined condition.
