應用單晶片dsPIC30F4011於PLC控制伺服馬達之實現
Implementation of PLC Control Servo Motor Using dsPIC30F4011
摘要
本實驗應用單晶片dsPIC30F4011完成伺服馬達定位控制之實現。此系統不像傳統PLC定位控制必須使用軸控卡與伺服馬達驅動器，並且可以與不同廠牌控制器整合成控制伺服馬達系統。本文所提到的伺服馬達控制系統應用三相六開關換流器的電壓空間向量調變技術，以六步方波空間向量查表法來做定位控制，使伺服馬達完成原點定位。當伺服馬達原點定位完成後，切換成正弦脈波寬度調變控制法以達到伺服馬達定位控制，結果顯示，伺服馬達控制的全程可以保持最大轉矩運轉並達成精準定位控制。本研究實現使用單晶片dsPIC30F4011完成伺服馬達定位控制系統，結論是能使馬達控制系統大幅降低成本並且縮小體積。

My thesis implements the control of PLC servo motor positioning with a dsPIC30F4011 single chip. This system is different from the traditional PLC control servo motor which requires Axis Control Card and Servo Driver. In addition, it can integrate with controllers which were made from different manufactories. The servo control system that was mentioned above uses voltage space vector modulation technology which is installed in a three-phase inverter with six power switch and controls positioning by space vector table method with six-step square wave to achieve servo motor’s original positioning. After the original positioning, switch to Sinusoidal pulse width modulation control method to control servo motor positioning. As a result, the whole process of the control of servo motor can maintain maximum torque and achieve accurate positioning. My study realizes the implementation of the dsPIC30F4011 single chip control system. As a conclusion, my thesis can substantially reduce costs and size when applying our motor control system.
