| Abstract: | This paper investigates a distributed extended state observer design and output feedback anti-disturbance control for nonlinear interconnected systems (ISs) with multiple disturbances. First, a distributed extended state observer with a sparse observer communication network is established to estimate the system states and external disturbances. Then, an output feedback controller with a disturbance compensation (DC) item is designed, where a novel dynamic memory event-triggered mechanism (DMETM) is proposed to save communication resources. Third, under the proposed controller, the closed-loop signals are bounded and the system states and the estimation errors converge to zero. Additionally, the system outputs satisfy |
