在近代的機械工程中有一波全電化的重大趨勢，舉凡航太、民生、交通、醫療上都有非常廣泛的應用，優點在於低噪音、潔淨、控制精度高且省能源，然而，大功率的馬達價格昂貴且取得不易，如全電式射出機之射出單元應用上，不少控制器廠商提出了以多軸驅動來取代大功率馬達的構想，其中有分為電機式同步驅動控制與機械性同步驅動控制，在電機式上講求驅動模組電路上的重新設計，在機械式上則講求特殊傳動元件與機械構造上的研發，兩者都要付出相當的研發成本才可達成目的，且同步控制模組產品之價格也相當昂貴，大多要搭配該控制器廠商之驅動器與伺服馬達才可應用之，基於上述理由，若能以不更動驅動模組電路及開發新傳動元件的方式來開發出同步驅動技術，將可大幅降低其研發成本與時間，並增加伺服驅動模組(驅動器、馬達)廠牌之選擇性。
本研究之控制策略為經上位控制器對雙軸進行同步誤差補償，配合最常用的工業時規皮帶傳動機構，建立出雙軸驅動系統，並使用市售驅動器所建立的常用功能，在最簡易的控制模式與連線上達到同步控制目的，研究中加入雙軸位置誤差和電流回授誤差進行補償，其中為因應電流訊號雜訊較大，建立電流平均濾波機制來做同步補償前之初步處理，且在對各項同步誤差(位置誤差、電流回授誤差)做分析與比較之後，驗證了電流回授平衡機制在雙軸驅動單元上之應用實益，其大幅度減少了扭矩損耗情形，並可避免驅動器發生電流過載之現象，最後實現了各項射出機實際上所使用的射出功能(單段射出、多段射出)，在以此技術為基之開發下，節省了研發成本與程式撰寫上之耗時性與困難度，並增加了伺服驅動模組廠牌上的選擇度。

In modern times,mechanical engineering it has a major trends of all-electric technology, such as aviation industry, livelihood, transportation, medical has many applications. It has the advantages of low noise, clean, high precision control and energy saving. Therefore,it is very expensive and that high-power motor is not easy to obtain. Such as applications of injection unit in all-electric injection molding machine,many industry put forward a multi-axis driving method to replace the a high-power motor, which are divided into electrical synchronous driving control and mechanical synchronous driving control, in the electrical it is focus on the redesign of driving module circuit. On the other hand,Mechanical is stresses on the R & D of special mechanical transmission elements and mechanical construction,both have to pay a considerable R & D costs, so that can be reach the goal,and the synchronization module poduct is very expensive,it must be used with the driver and servomotor that brands is the same to controller. Based on the above reason, if it can to be synchronize that don’t use above mothod.it can reduce the development cost and time, and then increase the selection of driver and servo motor.
Our control strategy of biaxial synchronization error compensation is through the supervisory controller, it is with the most commonly industrial timing belt transmission mechanism to establish a biaxial drive system. And it is using common functions of commercially driver, In the most simple control mode connection method to achieve the purposes of synchronization control,in this study we add biaxial position error and the current feedback error compensation, to respond to the noise of current signal we establish a average filtering mechanism of current to do initial treatment before the synchronous compensator. It verifide valuable of current feedback balance mechanism which apply in biaxial driving system Which greatly reduces the torque loss, and it can avoid the current overload of driver. Finally it realize the injection function(Single-injection,Muti-injection) of injection molding machine. Based on this skill, it was saved development costs and reduced time-consuming in programming,and increase the selection of the brands in driver module.
