Abstract

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.
