Abstract: An operation adjustment system includes estimation circuitry and generation circuitry. The estimation circuitry is configured to generate a calculation model based on a plurality of pairs of a parameter set and an evaluation index. The calculation model indicates a relationship between the parameter set and the evaluation index. The parameter set affects an operation of a motor control device. The evaluation index relates to a machine operated according to the parameter set by the motor control device. The generation circuitry is configured to generate a new parameter set based on the calculation model in order to update the calculation model with the new parameter set.
