Abstract :
In this paper, we analyze the stability of a class of interconnected systems with subsystem unmodeled dynamics and dynamic interactions employing decentralized adaptive controllers designed in [Wen, C., et al.] in the presence of actuator failures. It will be shown that the global stability of rest closed-loop system can still be achieved and the outputs can be regulated to zeros when some subsystems break down.
