在現代世界，環境保護與能源維護已經越來越重要。複合動力車輛(HEV)也因此有很大的發展。本論文將研究的重點放在並聯式複合電動重型機車之研發，我們使用一種新型並聯式複合系統，探討範圍包括車輛的電池即時充電器，鋰電池管理系統，以及整車的電控系統。在馬達的動力控制方面，我們設計了一個改良式輸出回授滑動模式控制器。此控制器保證系統的穩定性與強健性，並且只需要用到輸出變數，可大幅降低系統複雜度與成本並提升系統性能。本文所建立的新型並聯式複合動力車輛的電力系統與控制已經過實際的實驗平台驗證，實驗結果證明本方法的可行性與效用。

In a world where environment protection and energy conservation are growing concerns, the development of hybrid electric vehicles (HEV) has taken on an accelerated pace. We put our attention on the development and research of parallel hybrid electric heavy motorcycle. In this paper, electrical control system is mainly focused on a new parallel hybrid system; among them include car's using the instant battery charger, Li-ion battery management system and electrical control system. In the sliding mode motor control of the system, we design a modified output feedback controller. The controller using only output variable is proposed to stabilize the motor control system robustly. The variable structure system is asymptotically stable with better performance.
