  • 本論文將探討模糊控制及灰色預測應用於三軸機械手臂的運動控制。最近,模糊控制器已成新興的潮流,雖然其設計時很方便,但對機械手臂的設計,往往會有超越量的情形發生及較差的暫態和穩態響應。因此,針對這個問題,本論文將採取灰色預測當做前饋式補償器,如此設計的模糊控制器,當超越量產生之前,便以力量之補償方式降下來,可預防超越量的產生,並且於上升時間也有不錯的暫態響應及較小的穩態誤差,並且使用最佳化之演算法-基因演算法去調適灰色預測內重要參數ak,使整個系統設計更加完善。再進一步討論,將設計比例-微分-積分控制器,並且與提出的方法做比較及分析。此外,本論文使用模糊速度控制器去控制手臂的等速運動及防止干擾(如負載量的變化)。最後,發現在大部分實驗中,機械手臂均可達到預期目標,而且藉由視窗化的軟體,將所有實驗及設計均視窗化,以求達到良好的人機使用介面。本論文將在最後探討小部分結果不甚理想的原因,並提出未來可以改進的方向。
