Control Systems

1.8K
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.

Control Systems: Applications

1.1K
Electrical engineering plays a pivotal role in our daily lives, with control systems at the heart of many applications, from home appliances to sophisticated space shuttles. Control systems manage and regulate the behavior of devices and processes, ensuring they function safely, correctly, and efficiently.
In modern vehicles, control systems manage various functions to enhance performance and safety. The steering wheel and accelerator are primary inputs in a car's control system. The...

Feedback control systems

696
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...

Drug Distribution as One-Compartment Model and Elimination by Nonlinear Pharmacokinetics: Overview

338
Drug administration can occur through various routes, each of which may result in a different process of elimination. This process is often mixed with nonlinear and linear processes. It's important to understand that a single drug can be metabolized into different metabolites through parallel processes.
For instance, consider the metabolism of sodium salicylate. This compound is metabolized into two distinct substances: a glucuronide and a glycine conjugate. The rate of conjugation depends...

Neural Control of Respiration01:18

Neural Control of Respiration

4.7K
The neural regulation of respiration is a meticulously coordinated process primarily controlled by the respiratory centers located within the brainstem. These centers, composed of specialized neurons, transmit nerve impulses that control the contraction and relaxation of our respiratory muscles.
Respiratory Centers in the Brainstem
Two primary areas comprise the respiratory center: the medullary respiratory center in the medulla oblongata and the pontine respiratory group in the pons. The...

Open and closed-loop control systems01:17

Open and closed-loop control systems

1.6K
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...

    Area of Science:

    • Control Theory
    • Artificial Intelligence
    • Networked Systems

    Background:

    • Cooperative control of nonlinear multiagent systems is challenging due to unmodeled dynamics in followers.

    Main Methods:

    • A neural-networks-based adaptive control strategy is designed.
    • Lyapunov stability theory and algebraic graph theory are employed for stability analysis.
    • The control is fully distributed, requiring only local information exchange.

    Main Results:

    • The proposed strategy guarantees asymptotic synchronization of all followers to the leader.
    • Synchronization errors are maintained within a prescribed bound.
    • The control does not require knowledge of global graph properties.

    Conclusions:

    • The developed control strategy is effective for nonlinear multiagent systems with unmodeled dynamics.
    • The approach offers a robust and practical solution for distributed cooperative control.
    • Numerical examples validate the effectiveness and potential of the proposed techniques.
