Summary
This study addresses leader-based formation control in multiagent systems using asynchronous impulsive protocols with saturated feedback. It ensures stability and performance despite resource limitations and communication delays.
Area of Science:
- Control Theory

- Networked Systems
Background:
- Saturation phenomena limit system resources, impacting control performance.
- Impulsive protocols can reduce communication costs but introduce challenges.
- Leader-based formation control is crucial for coordinated multiagent systems.
Purpose of the Study:
- Investigate leader-based formation control for multiagent systems.
- Address challenges of asynchronous impulsive protocols and saturated feedback.
- Consider systems with and without time-varying delays.
Main Methods:
- Developed asynchronous impulsive protocols for communication at independent instants.
- Incorporated an offset for desired formation information.
- Analyzed general linear system models under asymmetric saturated feedback.
- Proved the existence and estimated admissible regions for saturated feedbacks.
Main Results:

Feedback control systems

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...

Open and closed-loop control systems
1.3K
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Multi-input and Multi-variable systems
266
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.

Automatic Processing and Automatic Social Behavior
120
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Solution Equilibrium and Saturation
20.8K
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...

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...
