Dr. Kristijan Hengster Movric, researcher at the University of Texas at Arlington, USA, gave a talk entitled “Cooperative Control of Multi-agent Systems – Stability, Optimality and Robustness”. This talk has brought together stability and optimality theory to design distributed cooperative control protocols that guarantee consensus in multi-agent systems and are globally optimal with respect to a positive semi-definite quadratic performance criterion.
Also, this talk was concerned with the effects of disturbances on multi-agent systems. Building on the classical results on the existence of Lyapunov functions for asymptotically stable systems and their use in assessing the effect the disturbances exert on those systems, Dr. Hengster Movric has shown that it is possible to extend such reasoning to partially stable systems, in particular those systems reaching consensus or synchronization.
