摘要

本系統以微電腦設計直流馬達位置控制系統，微電腦至馬達位置控制電路使用IEEE-488標準介面。
直流馬達之閉迴路控制採用速度回授與位置回授以達到高穩定度與高準確度。速度回授利用電壓與電流回授來模擬，而位置回授則由耦合至馬達轉軸之電位計所提供。
馬達位置控制電路之IEEE-488標凖介面採用PLA(Programmable Logic Array)設計，以便接到具有IEEE-488介面之電腦，完成之系統可以用個人電腦(PC)以軟體程式精確的由直流馬達控制旋轉輸盤移動到指定的位置。

A Closed-loop DC motor position control system using personal computer (PC) is designed and set up in the laboratory. The connection of PC to the Motor Position Control circuit uses IEEE-488 standard interface. The Programmable Logic Array (PLA) is used to design the IEEE-488 interface circuit for the Motor Position Control circuit.
Motor position control circuit loop uses both velocity feedback and position feedback to achieve high stability and high accuracy. A combination of current and voltage feedback is used to provide velocity feedback. A potentiometer with its shaft coupled to the motor is used to provide position feedback.
The complete set-up is established in the laboratory, and the result is an automatic angular position control system which uses PC in DC motor closed-loop position control with IEEE-488 standard interface.
