The bounded consensus problem for a class of nonlinear multiagent
systems with disturbances whose states are not measurable is achieved by
the event-triggered impulsive mechanism. Here, the observer is designed
to reconstruct the state of multiagent systems considering that this
state is unmeasurable. The bounded disturbance term is assumed to be an
unmeasurable dilated state component. Then, the dilated state observer
is designed for antidisturbance treatment. Appropriate trigger
conditions and Lyapunov functions are constructed based on the
event-triggered impulsive control method, and sufficient conditions for
multiagent systems are obtained to achieve bounded consensus. Zeno
behavior is eliminated under the control strategy. Numerical tests are
conducted to verify the validity of the control methods.
