Abstract
AbstractThis 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
performance. Finally, the simulation examples demonstrate the effectiveness of the DMETM in reducing the number of data transmissions compared to the dynamic event‐triggered mechanism (ETM).
