To provide a control parameter adjustment method and a control parameter adjustment system capable of suppressing occurrence of abrasions and breakdowns of device components by performing control corresponding to abnormalities occurred when adjusting a control parameter.SOLUTION: A control parameter adjustment method includes: a driving start process of starting driving of a plurality of driving systems by a position control device using a control parameter; an abnormality determination process of determining whether an abnormality has occurred after the driving of the plurality of driving systems started; and an adjustment process of collecting positioning data of each of the plurality of driving systems and evaluating feature quantity of the positioning data of each of the plurality of driving systems using a genetic algorithm to adjust the control parameter such that the evaluation value satisfies required performance. As the result of the abnormality determination process, the plurality of driving systems are stopped in response to determining that the abnormality has occurred.SELECTED DRAWING: Figure 3 【課題】制御パラメータの調整に際して発生した異常に対応した制御を行うことで、装置の部品の摩耗や破損の発生を抑制できる制御パラメータ調整方法及び制御パラメータ調整システムを提供すること。【解決手段】制御パラメータ調整方法は、制御パラメータを用いて位置制御装置により複数の駆動系の駆動を開始する駆動開始工程と、複数の駆動系の駆動を開始した後、異常が発生したか否かを判断する異常判断工程と、複数の駆動系の各々の位置決めデータを採取し、遺伝的アルゴリズムを用いて複数の駆動系の各々の位置決めデータの特徴量を評価して、その評価値が要求性能を満足するように制御パラメータを調整する調整工程と、を含む。異常判断工程の判断の結果、異常が発生したと判断したことに応じて、複数の駆動系を停止する。【選択図】図３
