Abstract:
The output feedback H∞ consensus control problem of multi-agent systems is studied
using an event-triggered control strategy. Two types of transmission delays, one from the
system output to the output feedback controller (OFC) and the other from the OFC to
the zero-order holder, are considered. This causes the OFC and the system not to be
updated in the same time intervals. An interval dividing approach is applied to such that
the whole system can be updated in the same time intervals. An event-triggered OFC with
H∞ performance is proposed for multi-agent systems to achieve consensus. By constructing
an appropriate Lyapunov–Krasovskii functional, sufficient conditions based on linear
matrix inequality are derived to guarantee the consensus achievement. Finally, the theoretical
results are validated using computer simulation.
