\begin{abstract}
This paper studies the practical fixed-time average consensus problem
for general continuous linear multi-agent systems under switching
topologies. Firstly, a distributed fixed-time consensus control protocol
based on dynamic event-triggered mechanism is designed by using the
local information exchange between individual agents. The protocol
introduces auxiliary dynamic variables, and the triggering condition
changes in real time based on the dynamic variable obtained online,
which can significantly reduce the number of triggering events,
effectively decrease the energy dissipation of the system and the update
frequency of the controller. Then, under the designed control protocol,
the sufficient conditions for the multi-agent system to solve the
practical fixed-time average consensus problem are given, and it is
proved that there is no Zeno behavior in the system. Finally, the
simulation results verify the effectiveness of the conclusions.%
