於馬達自動化繞線製程中,如何提升繞線品質一直為產業界所關心重要議題之一,而使馬達繞線具並排緊緻之特性則為馬達繞線品質提升之一關鍵因素。一般而言,精密的定位與穩定的張力為可否達成上述繞線品質要求的核心技術,然而,定位與張力之精度易受外在干擾現象影響(如機台振動)。有鑒於此,若欲改善張力與定位之控制性能,則必須藉由相關運動控制技巧之實現。本論文中,為提升繞線機各軸之定位精度,於定位控制上則搭配S-curve加減速規劃曲線,藉以避免過大加速度對定位精度之影響。在張力控制部份,相較於傳統張力調節裝置僅能被動的進行張力調整,本論文則發展一主動式張力控制系統以達到即時張力控制之目的。此外,為提升張力控制系統響應及消除繞線製程動作產生的週期性干擾源,本論文則進一步考慮具速度同動及反覆性學習控制之張力控制架構。同時,為避免系統參數變動影響張力控制系統性能,本論文則藉由遞迴式最小平方法來即時估測系統慣量等參數,並引入適應性控制之概念以調變合宜之控制器增益值。最後,將上述相關運動控制技術實現於一單槽內繞式馬達定子自動化繞線機之繞線製程上,藉以驗證本論文所提出各方法之可行性。
Regarding the automatic motor winding process, how to enhance the quality of winding is an important issue in the motor industry and thus rendering tidy motor winding crucial to the enhancement of winding quality. Generally speaking, accurate positioning and stable tension are core technologies in achieving high quality of winding. However, the precision of which is easily degraded by external disturbances (such as the vibration of the machine). Therefore, to improve the performance of tension control as well as position control of the automatic motor winding process, sophisticated motion control techniques are indispensible. In this thesis, to increase the precision of positioning on every axis of the automatic motor winding machine, S-curve motion planning is used to minimize the influence of excessive acceleration/deceleration on accuracy of positioning control. For tension control, in contrast to the traditional tension regulation device which can only passively regulate tension, in this thesis, an active tension control system is developed to conduct a real-time tension control. Furthermore, a tension control structure with speed synchronization and Iterative Learning Control (ILC) is proposed for improving the system response and eliminating periodic disturbance resulting from the periodic winding process. Additionally, the idea of adaptive control is exploited to adjust the controller gains based on the system parameters estimated by the Recursive Least Square (RLS) method in order to eliminate the influence of system parameter variation on the performance of tension control. Lastly, the aforementioned motion control techniques will be applied to the winding process of an automatic motor winding machine so as to verify the. feasibility of the proposed approach.
