The driving theme of Prof. Ayalew's research group is on modeling and control of dynamical systems with applications in energy systems, vehicle dynamics, traffic systems, automation and manufacturing. A comprehensive list of current and past sponsored research projects is given below. Downloadable links to papers from all of theses applications areas can be found from the publications tab. The following a synopsys of our current focus areas.

   

    I. Cooperative multi-agent/distributed perception and control for mixed vehicular traffic

 

    II. Interplay of vehicle dynamics and vehicular energy utilization management for unmanned on-road and off-road vehicle fleets

 

    III. Data-driven model-augmented approaches to vehicular energy management (learning optimal control policies from data for conventional and advanced powertrains (EV, HEV, etc)
