電動機車之馬達控制系統整合與遠端操控界面之製作

Abstract

電動機車的關鍵技術包括：電池、馬達及控制器。然而電動車的續航力不足，仍為其推展不利的主要問題。如何讓電池的運用更有效率便成為未來發展車控系統的主要目標。其中技術包含相位領先與能量回充兩大部份。本論文將針對相角提前的效率評估及這兩個主要技術的整合進行研究。其次，馬達控制器本身即具備序列埠的通訊，這讓我們能監視馬達的速度、電流狀態，並且透過介面送出馬達控制訊號。Java語言具有控制低階通訊的能力，並且其用於發展網路上的應用程式相當便利。結合上述的兩種特性，便能將我們的控制器透過Java撰寫的程式完成由通訊埠、Local端主機、網際網路這一連串的資料轉移，讓不同的遠端主機On-Line的從控制器讀回速度電流資及下達控制命令，達成遠端監控的功效。

The key technologies of an electric motorcycle are battery, motor, and controller. Due to the low energy density of the battery, current electric motorcycles have limited cruising range. Therefore, an efficient motor controller and energy management are very important. In this thesis, we investigate the phase-advance motor control strategy and energy-reuse techniques to enhance the efficiency. Further, the study also uses a serial port to monitor motor speed, current status, and send system commands to the controller. Java is used to build the interface which is capable of low-level communication as well as network applications. As a result, we could transmit information to remote host via serial port, local host, and Internet.
