臺灣博碩士論文加值系統

本論文建立以單軸滾珠導螺桿為進給系統，在具有多自由度的考慮下之伺服控制模型。目的為建立進給系統的運動方程式，了解運動位移組成模型，以作為工具機進給控制其參數選擇之使用依據。先求解特徵值、特徵向量及動態響應，觀察運動模型之頻率響應峰值之組成，比較未加入與加入伺服端控制器所建構的運動模型所產生動態響應。並調整伺服端控制器參數，觀察其動態響應及效果。以期在模型建立後，可以提供國內工具機業者，放入相關的機械結構與控制器參數後，在進行實機控制器參數調整時，根據模擬的參數改變，進行系統在不同模態的相位增益、阻尼、頻寬等調機之依據。

To build a servo control model of a single-axis ball screw feed system with multi DOF consideration, this thesis establishes the dynamic system equation. The solution of the eigenvalues and eigenvectors shows the feed system consisting of several peaks in different mode shapes. Difference between the frequency response by adding the servo controller loop or not with the servo tuning are discussed. Solution of developed system mode shapes and dynamic frequency response provides an approach for control parameter’s tuning of a CNC machine. Such phase margin, damping effect, frequency bandwidth and associated mode shapes of the system are resolved.
