Abstract

This paper explores a practical perspective on the distributed H∞ control strategy for limited-time control challenges in massively interrelated systems. For a specific type of massively interrelated systems characterized by a networked topological configuration, a robust, distributed control method for limited-time H∞ connectivity stabilization, using dynamic feedback and addressing multiple overlaps, is proposed. It expands the state space of power systems and decomposes the system into a sequence of coupled subsystems in reverse order. Firstly, a distributed limited-time H∞ dynamic feedback controller is designed for the subsystem, and then the designed repetitive controllers are compressed into the initial area. The synchronization of control strategies can be accomplished, and the system can be continuously stabilized in limited-time H∞. Ultimately, the introduced approach is employed in a four-region interrelated system featuring a network architecture, and simulation outcomes validate both its practicality and efficacy. This study investigates the distributed limited-time H∞ control of massively interrelated systems from an innovative viewpoint. This paper introduces a novel method for stabilizing massively interrelated, networked systems. It uses dynamic feedback, is robust and distributed, ensuring limited-time H∞ stability. This involves expanding the system's scope and dividing it into coupled subsystems in a periodic reversal order. Firstly, a distributed limited-time H∞ dynamic feedback controller is developed for the subsystem. Afterwards, the duplicated controllers are compressed back into the original area. Control algorithms can be synchronized. The law of contract can guarantee the continued stability of the system within a specific time frame, as quantified by H∞. The proposed method is ultimately implemented on a networked four-region interrelated system, and the modeling outcomes clearly showcase the practicality and efficacy of the suggested approach.
