Abstract
The variation of deviations of actual positions of a moving body from corresponding command positions is quantitatively evaluated as a servo control error, whether a feedback control system is oscillating is decided on the basis of the servo control error, set values of parameters expressing characteristics of a closed loop or a control element included in the feedback control system are adjusted on the basis of the result of the decision whether the feedback control system is oscillating, and the values of the parameters are adjusted to optimum values slightly different from values which will cause the feedback control system to oscillate.
