The project output filled in the gap in the theoretical study of the hierarchical optimal energy management strategy to promote its application for energy management of electric vehicles. The project was multidisciplinary and at the forefront of electrics, control science, information, and communication technologies, and was also important from the aspects of both fundamental theories and applications. The project has combined the state-of-the-art control, optimization, numerical simulation, and real-time hardware experimentation. In addition, a mass of battery control techniques has emerged as an extension of the study. The project dramatically improves the role of controlling techniques in performance promotion of electric vehicles. The main innovation outputs lie in the establishment of an integrated hierarchical optimal energy management of electric vehicles. The fellow fully incorporated the state-of-the-art control algorithms and the high nonlinear time-varying characteristics of vehicle powertrain to supply high-quality energy control of electric vehicles, thereby improving their operation economy and extending the battery lifespan. Also, the outstanding outputs in battery control enables the controlling performance promotion of lithium-ion batteries equipped in electric vehicles. The research outputs will contribute to both control theory and applications in electric vehicles with extensions to other engineering problems going forward. The developed control framework is generic and can be extended for a broad class of engineering problems, which need to be optimally controlled with multiple objectives and subject to complicated nonlinearities and constraints.
After the high-quality research at QMUL, the fellow published 44 papers in top journals. These papers are open access. Based on the project support, the fellow not only finished all the designated research tasks, but also extended the research to intelligent connected vehicles and advanced lithium-ion battery control. In addition, the fellow attended a few international conferences (even with the huge challenges as a result of COVID-19 pandemic), including the 34th World Electric Vehicle Symposium & Exhibition, the 4th CAA International Conference on Vehicular Control and Intelligence, and MSCA European Green Deal cluster, to disseminate research output. The fellow won the Excellent Paper Award in EVS34. The fellow was elected to the Fellow of Institution of Engineering and Technology, due to his outstanding contributions to optimal control of electric vehicles. The fellow was also elected to an editor of two journals: IEEE Access and Vehicles.
