Cooperative Fault-Tolerant Output Regulation of Linear Heterogeneous Multiagent Systems via an Adaptive Dynamic...

Area of Science:

• Control Systems Engineering
• Multiagent Systems Theory
• Fault-Tolerant Control

Background:

• Cooperative fault-tolerant output regulation is crucial for linear heterogeneous multiagent systems facing actuator faults.
• Existing methods often require global information or continuous communication, limiting practical application.

Purpose of the Study:

• To develop an adaptive dynamic event-triggered control (ETC) scheme for cooperative fault-tolerant output regulation.
• To enable intermittent communication in multiagent systems, reducing communication load and energy consumption.
• To address systems where exosystem matrices are only partially known by followers.

Main Methods:

• An adaptive dynamic event-triggered scheme is proposed, utilizing dynamic variables for a more general event-triggering condition.
• The approach avoids the need for all agents' system matrices to be identical or known a priori.
• It removes the assumption of global information availability for controller design.

Main Results:

• The proposed ETC method achieves cooperative fault-tolerant output regulation in a distributed manner.
• Intermittent communication is successfully implemented, excluding Zeno behavior.
• The adaptive dynamic event-triggered condition offers potential for energy savings and enhanced performance compared to static or periodic methods.

Conclusions:

• The developed adaptive dynamic ETC strategy effectively addresses cooperative fault-tolerant output regulation in linear heterogeneous multiagent systems with actuator faults.
• The scheme facilitates distributed control with intermittent communication, offering advantages in energy efficiency and performance.
• Simulation results validate the efficacy of the proposed fault-tolerant control strategy.
