Fully Distributed Observer-Based Leader-Following Consensus of Linear Multiagent Systems by Adaptive Dynamic
IEEE Transactions on Cybernetics
|November 11, 2024
Summary
This study introduces adaptive dynamic event-triggered (ADET) strategies for multiagent systems (MASs) to achieve leader-following consensus efficiently. These novel distributed methods reduce communication load while ensuring system stability and performance.
Area of Science:
- Control Theory
- Networked Systems
- Robotics
Background:
- Investigating consensus control in general linear multiagent systems (MASs) is crucial for coordinated behaviors.
- Event-triggered communication (ETC) aims to reduce communication load by transmitting data only when necessary.
Purpose of the Study:
- To propose novel adaptive dynamic event-triggered (ADET) strategies for leader-following consensus in MASs.
- To develop distributed control protocols that do not require global information or knowledge of network size.
Main Methods:
- Developed two ADET strategies: one for synchronous ETC and one for asynchronous ETC.
- Introduced adaptive triggering parameters and time-varying thresholds for enhanced flexibility.
- Designed corresponding control protocols for the proposed ADET strategies.
Main Results:
- Achieved leader-following consensus in general linear MASs using fully distributed ADET strategies.
- Demonstrated that the proposed methods do not require global information or network size.
- Showcased the flexibility of asynchronous ETC for improved information transmission.
Conclusions:
- The proposed ADET strategies offer an effective and distributed approach to leader-following consensus in MASs.
- Comparative analysis highlights the efficiencies and specific applications of observer-based versus state-based ADET algorithms.
- Simulative examples validate the practical effectiveness of the developed strategies.

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...

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:

Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.

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...

01:58Cooperative Allosteric Transitions
7.9K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...
