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

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.
