FEEDBACK CONTROL Meaning and
Definition
-
Feedback control is a term commonly used in the field of engineering and systems theory to describe a process or technique where the output or behavior of a system is continuously monitored and adjusted based on measured information about its performance. It refers to a control mechanism that utilizes feedback loops to ensure that the system's output matches a desired reference or setpoint.
In feedback control systems, the system's output is compared to the desired output or reference input using a sensor or measurement device. This comparison generates an error signal, which is fed back to a controller. The controller calculates and implements necessary adjustments to the system's inputs or parameters to minimize the error and bring the output closer to the reference value.
The adjustment or corrective action initiated by the controller is based on predefined rules, algorithms, or mathematical models designed to optimize system performance. The feedback loop continuously updates the controller with new measurements, constantly assessing and improving the system's behavior.
Feedback control systems are widely used in various applications, such as industrial processes, mechanical systems, electronics, and automation. They enhance a system's stability, accuracy, and responsiveness, allowing for efficient and precise control of its output. By continuously monitoring and adjusting, feedback control ensures ongoing optimization and adaptation to changing conditions, making it an essential tool for achieving desired performance in complex systems.

Etymology of FEEDBACK CONTROL
The term "feedback control" is typically used in the context of control systems engineering.
The word "feedback" is derived from the Greek word "phébé" meaning "inform, tell". In control systems, "feedback" refers to the process of returning a portion of the output of a system back to the input for modification or adjustment. This concept of feeding back information to the input for control purposes was first introduced in the field of telecommunications.
The term "control" comes from the Latin word "controllare", which means "to check, regulate, or restrain". In the context of control systems engineering, "control" refers to the process of monitoring and adjusting the behavior of a system to achieve desired outcomes.
So, the etymology of "feedback control" combines the idea of returning information to the input for adjustment or modification (feedback) and the process of monitoring or regulating a system's behavior (control).
