Xiaotian Dai is currently a PhD candidate in the Real-Time Systems (RTS) Group, University of York, UK. He joined the RTS group in 2015, supervised by Prof. Alan Burns and Prof. Neil Audsley (internal). His research involves cooperatively design of control system and real-time scheduling for Cyber-Physical Systems (CPS). Multiple methods are proposed and implemented to investigate the scheduling impact on control performance. Tradeoffs between scheduling and control are made by a dual-period task model and a flexible adaptation process. This method is interdisciplinary with real-time scheduling theory, control theory and machine learning.
Xiaotian Dai started to design and develop robots since 2010. He was involved in many autonomous robot research and he is continuously working on implementing UGVs as well as running simulations. He believes robots will shape the future of how human work and live, and it is important to learn to how to interact, share and cooperate with them.
