Although fully electric vehicles have been used for small payload or limited range applications, the production of long range, high payload electric vehicles will require decades of research and development. To aid in bridging the gap between gas powered and fully electric vehicles, hybrid electric vehicles for marine and aviation applications can increase vehicle electrification while reducing the necessary technological leaps in areas such as energy density. These hybrid-electric vehicles incorporate turbine generators, drive motors, and energy storage systems which require decisions on optimal power distribution between components. Similar to electric vehicles, the electric drive components and vehicle power electronics also require thermal management to prevent the thermal related electronics failures prevalent in electrified systems.
The dynamics of these vehicles create control challenges in both the electrical and thermal domains, as the vehicle objectives (trajectory, cost, etc.) cannot be compromised to accommodate the constraints and requirements of the subsystems (maximum temperature, power required, etc.). Additionally, these subsystems operate on unique timescales, causing a centralized controller to be insufficient to provide optimal performance for each domain and subsystem. Past work within the Alleyne Research Group has demonstrated the success of hierarchical model predictive control for these multi-domain, varying-timescale control challenges, and a similar technique can be applied to hybrid-electric vehicle applications. A hierarchical model predictive control strategy allows for primary objectives and constraints of the system with slower dynamics, such as trajectory or motor temperature, to be governed by high-level controllers; however, domains with quicker dynamics, such as power distribution from an electrical bus, can be controlled by low-level, short-timescale controllers.
Reid will work on utilizing the graph-based modeling framework to develop computationally efficient models for aircraft turbomachinery. These efficient models will be used to facilitate the optimal design and control of an aircraft propulsion, air cycle, and power generation system.
