Summary
This study presents a new control method for multi-agent systems (MASs) to ensure resilient containment control under denial of service (DoS) attacks. The approach uses an event-triggered mechanism and disturbance observers for efficient and secure system operation.
Area of Science:
- Control Theory
- Networked Systems
- Cybersecurity
Background:
- Multi-agent systems (MASs) face challenges in maintaining coordinated control under adversarial conditions.
- Denial of Service (DoS) attacks and external disturbances degrade system performance and security.
- Existing control strategies may incur high communication burdens or lack resilience.
Purpose of the Study:
- To investigate the prescribed-time resilient containment control (PTRCC) problem for MASs.
- To develop a control strategy resilient to DoS attacks and disturbances.
- To achieve containment control within a user-defined prescribed time.
Main Methods:
- A novel resilient dynamic event-triggered mechanism (RDETM) is proposed to reduce communication load.
- Disturbance observers are integrated to actively compensate for external disturbances.
- A prescribed-time resilient containment controller is designed for follower agents.
Main Results:
- The RDETM adaptively adjusts thresholds to minimize transmissions during DoS attacks while preventing Zeno behavior.
- The integrated disturbance observers effectively counteract external disturbances.
- Theoretical analysis confirms the achievement of the containment control objective within the prescribed time.
Conclusions:
- The proposed control strategy ensures prescribed-time resilient containment control for MASs.
- The developed RDETM enhances communication efficiency and system resilience.
- Simulation results validate the effectiveness of the approach against DoS attacks and disturbances.

01:26Reclosers and Fuses
Automatic circuit reclosers enhance the protection of distribution circuits by interrupting and auto-reclosing an AC circuit according to a preset sequence. They effectively manage temporary faults on overhead distribution lines, often caused by tree limbs or wildlife, by briefly disrupting service to improve overall reliability. However, contact with reclosers or energized broken conductors on the ground can pose serious hazards.

01:27Line Protection with Impedance Relays
Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.

01:23Radial System Protection
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

01:16Zones of Protection
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

01:26Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
