Distributed fault estimation observer design for multi‐agent systems with switching topologies

A distributed fault estimation observer (DFEO) design is studied for multi‐agent systems with switching topologies. Firstly, a local fault estimation observer is presented for each agent system based on the relative output estimation error. Then by introducing global variables, a global fault estimation observer is proposed by utilising the average dwell‐time technique. Furthermore, a dissipativity‐based distributed observer is presented to handle external disturbances. Finally, simulation results are presented to illustrate the feasibility and effectiveness of the proposed DFEO strategy.
