本文主要研究為三自由度並聯式機械臂的運動控制,透過三軸滑塊與工作平台之位置求其運動方程式,並分析其工作空間,最後利用順滑模態控制器控制平台進行圓形軌跡運動。本文一開始會針對此機械臂進行運動學分析,包括座標軸的建立、順逆向運動學推導以及工作空間模型之建立,並且推導馬達的動態方程式,以便於順滑模態控制器的設計。最後使用傳統順滑模態控制器進行頻率為0.2Hz、半徑為150mm的圓軌跡追蹤實驗,實驗結果顯示可將平台位置誤差控制在8mm以下;而進行同樣頻率、半徑為50mm的圓軌跡追蹤實驗,則可將平台位置誤差控制在6mm以下;後來改用PI型順滑模態控制器進行同為頻率0.2Hz、半徑150mm的圓軌跡追蹤實驗時,平台位置誤差降至0.7mm以下,證實PI型順滑模態控制器較傳統順滑模態控制器具有較高的強健性。
The aim of the thesis are the analysis of the 3-DOF parallel manipulator including the workspace and the kinematics, and the motion control. With the geometric relationship of the platform and the slider, we can obtain the kinematics.
Then the sliding mode controller is designed. The experiment result of the circle tracking shows that the error of the platform is beneath 0.7 mm.
