Background

  • Multiagent systems (MASs) face challenges like denial-of-service (DoS) attacks and actuator faults, impacting consensus.
  • Achieving resilient practical leader-follower bipartite output consensus (LFBOC) in heterogeneous linear MASs is crucial for reliable operation.
  • Existing methods often require global information or lack integrated fault tolerance and event-triggered mechanisms.

Purpose Of The Study

  • To investigate the fully distributed resilient practical LFBOC problem for heterogeneous linear MASs.
  • To develop novel adaptive event-triggered observers and fault-tolerant controllers to mitigate DoS attacks and actuator faults.
  • To propose a method that avoids global information and integrates event-triggered communication with discrete updates.

Main Methods

  • Design of two novel adaptive event-triggered observers to estimate leader matrix and state under DoS attacks.
  • Development of an adaptive event-triggered fault-tolerant controller to achieve LFBOC without chattering.
  • Implementation of distributed, event-triggered communication and discrete controller updates.

Main Results

  • Successfully addressed the LFBOC problem in MASs under simultaneous DoS attacks and actuator faults.
  • The proposed observers and controller effectively estimate system states and ensure consensus.
  • Demonstrated the method's effectiveness through a practical example, confirming its resilience and distributed nature.

Conclusions

  • The developed adaptive event-triggered observers and fault-tolerant controller provide a robust solution for LFBOC in MASs.
  • The proposed distributed approach enhances system resilience against cyber-attacks and component failures.
  • This method offers a practical and efficient solution without relying on global information.

Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...

In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Elastic collision of a system demands conservation of both momentum and kinetic energy. To solve problems involving one-dimensional elastic collisions between two objects, the equations for conservation of momentum and conservation of internal kinetic energy can be used. For the two objects, the sum of momentum before the collision equals the total momentum after the collision. An elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals...

Proportional-Derivative (PD) control is a widely used control method in various engineering systems to enhance stability and performance. In a system with only proportional control, common issues include high maximum overshoot and oscillation, observed in both the error signal and its rate of change. This behavior can be divided into three distinct phases: initial overshoot, subsequent undershoot, and gradual stabilization.
Consider the example of control of motor torque. Initially, a positive...
