在本研究中,針對所探討之主從式控制架構,主從式控制廣泛應用在業界當中,主要是該控制架構簡單,並通常透過簡單的參數調整過程即可獲得不錯的軸向同動控制,在工具機剛性攻牙的過程中,移動軸需配合主軸轉速進行同動控制,因此,本研究中決定移動軸控制參數來做為田口式實驗法之因子,以田口式實驗法進行探討連續型參數調整,改善剛性攻牙所造成的同動誤差。首先,利用驅動器內部自動調整增益模式,先找出一組適當的參數當作初始控制參數,再藉由田口式實驗法全因子直交表透過系統與實際作業環境進行互動操作程序以進行連續型參數調整調,並且以一階迴歸式所得到參數改善同動誤差,兩者結果比較田口實驗與迴歸分析之最佳參數兩者同動誤差值比較可證實迴歸效果比田口最佳參數組合所改善效果較顯著。
This study developed a method for the adjustment of servo control parameters based on a master-slave control structure to reduce synchronous errors during rigid tapping processes. The developed adjustment method first uses the in-built auto-tuning function of the applied servomotor pack to obtain a set of servo control parameters to be used as the initial values of the adjustment method. Then, the best set of servo control parameters is obtained using the Taguchi method, which performs several experiments with rigid tapping processes. Further, the regression analysis algorithm is applied to the obtained best set of servo control parameters for discussing and finalizing the optimal settings of continuous control parameters.
