Leader-Following Consensus of Linear Multiagent Systems With Aperiodically Sampled Outputs: A Distributed
IEEE Transactions on Cybernetics
|October 23, 2024
Summary
This study introduces a new leader-following consensus protocol for linear multiagent systems using sporadic output data. The novel impulsive observer design is robust to denial-of-service attacks.
Area of Science:
- Control Systems Engineering
- Networked Systems
Background:
- Consensus problems are crucial for multiagent systems coordination.
- Existing methods often require continuous communication or fixed sampling.
Purpose of the Study:
- To develop a distributed consensus protocol for linear multiagent systems with aperiodically sampled outputs.
- To design an impulsive observer with gains decoupled from network topology.
Main Methods:
- A novel distributed impulsive-observer-based consensus protocol is proposed.
- Time-varying Lyapunov function techniques are used to establish exponential stability conditions for impulsive systems.
- The resilience against denial-of-service (DoS) attacks is analyzed.
Main Results:
- Sufficient conditions for exponential stability of linear impulsive systems are derived.
- The impulsive observer gain is decoupled from graph properties, allowing reusability across different network topologies.
- The protocol demonstrates robustness against low-frequency DoS attacks in the observer communication network.
Conclusions:
- The proposed protocol effectively achieves leader-following consensus for linear multiagent systems with aperiodic sampling.
- The decoupled observer design offers flexibility and simplifies implementation.
- The system exhibits resilience to certain types of denial-of-service attacks.

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Nonlinear systems often require sophisticated approaches for accurate modeling and analysis, with state-space representation being particularly effective. This method is especially useful for systems where variables and parameters vary with time or operating conditions, such as in a simple pendulum or a translational mechanical system with nonlinear springs.

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be...
