Cooperative Control of Multiple Agents with Unknown High-frequency Gain Signs under Unbalanced and Switching Topologies
Qingling Wang, Haris E. Psillakis, Changyin Sun
Existing results on cooperative control of multi-agent systems with unknown control directions require that the underlying topology is either fixed with a strongly connected graph…
PI Consensus Error Transformation for Adaptive Cooperative Control of Nonlinear Multi-Agent Systems
Haris E. Psillakis
A solution is provided in this note for the adaptive consensus problem of nonlinear multi-agent systems with unknown and non-identical control directions assuming a strongly connec…
Robustness of the nonlinear PI control method to ignored actuator dynamics
Haris E. Psillakis
This note examines the robustness properties of the nonlinear PI control method to ignored actuator dynamics. It is proven that global boundedness and regulation can be achieved fo…
An extension of the Georgiou-Smith example: Boundedness and attractivity in the presence of unmodelled dynamics via nonlinear PI control
Haris E. Psillakis
In this paper, a nonlinear extension of the Georgiou-Smith system is considered and robustness results are proved for a class of nonlinear PI controllers with respect to fast paras…
