A comparative study of different control strategies for the "ECO" electric vehicle drive train

点击翻译按钮获取中文摘要

One of the most selling features of electric vehicles (EV) is their power train working efficiency and/or its energy consumption. There is relentless effort in the market to improve on both aspects. The role of power electronics is vital to guarantee efficient operation in motoring/cruising/braking modes of the EV operation within any drive cycle. In-Motive engineering is focused on the development of not only a cost effective power train but also an efficient and energy conservative one. The UOIT expertise will complement and support In-Motive's to achieve this goal. The project will involve the modeling and simulation of the In-Motive power train with different inverter/motor/transmission system control scenarios. The project will detail the pros and cons of using vector control, direct torque control, and the novel self-sustained control to manage the operation of the EV power train; one at a time. This comparison will highlight the different controllers working features; for example, space envelope of the implemented control system, working efficiency, level of energy consumption, safety, reliability, availability, and maintainability of the system.
