多功能數位訊號處理器電路板設計與其在低轉速馬達上之應用

Abstract

本論文利用德州儀器公司生產的TMS320C50晶片架構一個多用途的數 位訊號處理器 電路板，並為其在個人電腦端設計了一塊平行雙向通訊 介面卡，與伺服馬達控制電路板。結合這三者，可成為一完整的伺服馬達 控制環境。另外，針對伺服馬達系統在低轉速時，受到摩擦力影響造成轉 速不穩定的現象，將定時取樣改由定點取樣的方式來估測伺服系統的轉速 ，並藉控制來改善伺服馬達轉速的變化。最後，在多組數據中比較實驗的 結果。 In this thesis, we design a general purpose DSP board based on TMS320C50 chip made by Texas Instruments, a bi-directional parallel data transfer interface on personal computer to communicate with this board, and an interface circuit for servo control. This system is implemented on a motor speed control experiment. Particularly, we focus on the low-speed control where the stiction and friction effects are prominent. In experiment, the fix-position sample method is used to estimate the rotation speed instead of the fix-time sample method. The quantization issue and experimental results are discussed.
