由於電腦工業的發達，PC-Based控制應用成為自動化控制領域的常見控制架構，無論透過數位脈波位置命令、類比速度或扭力命令皆成為泛用標準介面；隨著資訊產業網路技術的成熟，自動化業界亦開始導入即時網路技術於伺服傳輸介面上，本研究論文即在探討即時網路的優缺點與驗證之。
即時網路介面目前處於萌芽期，百家爭鳴，本論文採用日本三菱電機的 SSCNet技術來從事運動控制，並利用工研院EPCIO技術從事遠端輸出入控制，來建構具嵌入式與分散式優點的控制系統硬體架構，並採用Win+RTX的軟體即時性架構，發展硬體驅動函式庫與控制系統軟體。藉由控制具六自由度的串並聯線性馬達定位平台，除實務設計插值器、加減速規劃、位置控制器與運動解轉換矩陣外，重點放在即時網路伺服介面特有的：省配線與抗干擾、具高解析度的控制命令與回授、驅動器參數管理與即時修改等，這些特點有助於未來高階性能控制器的研發。

This thesis discussed the issues related to the advantages of hard real-time servo net and presenting the proof of the result. Due to the development of computer industry, PC-Based Controller has become the common control architecture in automatic control field. Such as digital pulse command, analog velocity and torque command are generally used in servo control system. Meanwhile, with the maturity of the I.T. (Internet Technology), the automatic industry has applied the hard real-time I.T. to servo control interface.
At present, the servo net is on the initial stage. The subject matter of this paper is to adopt Mitsubishi SSCNet (Servo System Control Net) to design SSCNet interface card for motion control and ITRI EPCIO (Exquisite Position Control and Inputs/Outputs) for remote I/O control, along with a real-time multi-tasking kernel (RTX) under the Microsoft Window 2000/XP. Both SSCNet card and remote I/O module are embedded and distributed. By the controlling of a 6-DOF hybrid-type alignment positioning stage, which contains 5 axes of Mitsubishi Linear motors and 1 axes of Oriental step motor. Except for the interpolation methods, acceleration/deceleration, controller and inverse kinematics are designed in the application software system, it is emphasized on the easy expansion, simple wiring, anti-interference, high-resolution servo command and feedback, driver parameter management and real-time modifying on host PC, etc., and real-time servo net control will become the major approach in development of high-performance motion control system.
