Area of Science:

• Control Systems Engineering
• Nonlinear Dynamics
• Multiagent Systems

Background:

• Cooperative output regulation is crucial for multiagent systems.
• Existing methods face challenges with uncertainty and digital implementation.
• Event-triggered control offers potential for efficiency but requires careful design.

Purpose of the Study:

• To solve the cooperative global robust practical output regulation problem.
• To develop a distributed event-triggered state feedback control strategy.
• To handle second-order uncertain nonlinear multiagent systems.

Main Methods:

• Design of two novel distributed internal models for each agent.
• Development of a distributed event-triggered control law and mechanism.
• Recursive design of control laws based on sampled states.

Main Results:

• The proposed control strategy effectively regulates outputs in uncertain systems.
• The event-triggered mechanism prevents Zeno behavior.
• Tracking error bounds can be made arbitrarily small by adjusting a design parameter.

Conclusions:

• The study presents a viable solution for robust practical output regulation in complex multiagent systems.
• The proposed event-triggered approach enhances control efficiency and robustness.
• The findings are validated through illustrative examples.
