臺灣博碩士論文加值系統

本論文先針對軟性邊界接觸力進行分析研究。由於軟性邊界物理特性與彈簧
物理特性相似，故以彈簧模型取代軟性邊界模型進行方程式推導。整體架構包括
運動平台及軟性邊界接觸力藉自由體圖推導出系統模型，其中有些參數不易直接
量測，則以頻率響應方法進行系統鑑別以取得系統參數。針對此系統硬體架構上
之限制及控制性能以根軌跡設計PD控制器進行力量控制，並以頻率響應方法對
閉迴路系統加以分析，再以軟體模擬其系統響應。最後以DSP作為控制核心，
進行實驗驗證。

The model of contact force on flexible boundary is built by using the spring model, since the response of flexible boundary is similar to a spring. A complete model includes linear stage, force sensor, contact head and flexible boundary is constructed by taking free body diagram. Some parameters are impossible to be measured directly. These unknown parameters are obtained by system identification in frequency domain. Using root-locus technique, a PD controller is designed to control the contact force based upon the hardware constraints and desired performance. After analysis being performed in frequency domain and software simulation, a DSP based real-time feedback contact force control system is implemented. The desired performance and the characteristics of contact force control system on flexible boundary are verified in experiments.
