## Research

Ulsoy's research work focuses on several areas: dynamics and control (adaptive control, state derivative feedback, coupling between modeling and controller design, time-delayed systems), manufacturing automation (sawing, turning, milling, drilling, robotics, stamping), reconfigurable systems, mechatronics, automotive systems (accessory drive belts, active suspensions, vehicle lateral control) and other engineering systems, like disk drives and mineral processing operations.
His basic research contributions in dynamics and control have led to numerous best paper awards, and he is one of the first researchers to apply methods from advanced control theory to manufacturing systems.
His research work has had impact on industry: Accessory drive belts and active safety systems in automobiles worldwide utilize methods and technologies that he has developed. Reconfigurable manufacturing systems, of which he is a co-inventor, have been widely adopted in industry.
Other commercial systems influenced by his research are: design of bandsaw blades, design and control of drills, control of machine tools, automotive suspensions, stamping presses, disk drives, and ground robots.
Upon receiving the Turkish Scientific and Technological Research Council (TÜBİTAK) Special Award in 2012, his research work was described:
   For his exemplary research on dynamic systems and automatic control, including dynamic analysis and control of axially rotating and translating elastic systems and application of advanced control theory to manufacturing and automotive systems.
