Observer-Based Dynamic Event-Triggered Semiglobal Bipartite Consensus of Linear Multi-Agent Systems With Input
IEEE Transactions on Cybernetics
|April 19, 2022
Summary
This study introduces observer-based dynamic event-triggered control for linear multi-agent systems with input saturation. The proposed methods achieve semiglobal bipartite consensus, avoiding Zeno behavior.
Area of Science:
- Control Theory
- Systems Engineering
- Networked Systems
Background:
- Multi-agent systems (MASs) face challenges like input saturation and competitive networks.
- Achieving consensus in MASs is crucial for coordinated behavior.
- Observer-based control is needed when states are not directly measurable.
Purpose of the Study:
- To investigate observer-based dynamic event-triggered semiglobal bipartite consensus (SGBC) for linear MASs.
- To develop distributed dynamic event-triggered control (DETC) protocols for MASs with input saturation.
- To ensure consensus is achieved without Zeno behavior.
Main Methods:
- Utilizing estimated relative information and low-gain feedback.
- Designing distributed dynamic event-triggered control (DETC) protocols.
- Applying gauge transformation and Lyapunov theory for consensus conditions.
- Employing observer-based dynamic event-triggered control.
Main Results:
- Semiglobal bipartite consensus (SGBC) is achieved for MASs under fixed and jointly connected topologies.
- The proposed DETC protocols effectively solve the SGBC problem.
- Bipartite consensus conditions are derived using gauge transformation and Lyapunov theory.
- Zeno behaviors are successfully excluded in the proposed control strategies.
Conclusions:
- The developed observer-based dynamic event-triggered control protocols enable SGBC in linear MASs with input saturation.
- The theoretical findings are validated through simulation examples.
- The research contributes to robust consensus control in networked systems.

Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...

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.

System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

Drugs administered through various routes can lead to nonlinear elimination, resulting in complex pharmacokinetic behaviors crucial to understanding efficacious drug dosing.
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...

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:
