Understanding Feedback Control of Dynamic Systems
What is Feedback Control?
Feedback control is a fundamental concept in control systems engineering, where a portion of the system's output is fed back to the input to regulate the system's behavior. This mechanism aims to maintain a desired output despite disturbances or uncertainties within the system. Feedback control systems are prevalent in various industries, including aerospace, manufacturing, automotive, and robotics.
Dynamic Systems and Their Significance
A dynamic system is one whose state variables change over time in response to inputs and internal dynamics. These systems can be linear or nonlinear, time-invariant or time-varying. Understanding the dynamic nature of systems is critical for designing controllers that can stabilize and optimize their performance.
