You are describing a closed-loop control system. This system continuously monitors the output and adjusts the input to maintain the output at the desired level by using feedback from the process.
Feedback in cybernetics refers to the process of a system receiving and responding to information about its output in order to maintain or regulate its behavior. In control systems, feedback is used to monitor and adjust the system's performance by comparing the actual output with the desired reference input. This allows for self-regulation and correction to achieve the desired outcome.
Positive feedback tends to magnify a process or increase its output by reinforcing and amplifying the desired behavior or outcome. This can lead to exponential growth or improvement in the system or process.
The correct order of elements in a control system typically follows this sequence: the sensor, which measures the output and provides feedback; the controller, which processes the feedback and determines the necessary adjustments; the actuator, which implements the changes in the system; and finally, the process or system itself that is being controlled. This sequence ensures that the system can accurately monitor and adjust its behavior to meet desired performance criteria.
The role is to monitor the input, process, and output so that the system can adjust itself to meet the goal.
Some possible causes of a process being out of control include incorrect calibration of equipment, variations in raw materials, operator error, or environmental factors. It is important to regularly monitor and analyze process data to detect and address any deviations from the desired control limits.
Feedback in cybernetics refers to the process of a system receiving and responding to information about its output in order to maintain or regulate its behavior. In control systems, feedback is used to monitor and adjust the system's performance by comparing the actual output with the desired reference input. This allows for self-regulation and correction to achieve the desired outcome.
Self-regulating control mechanisms usually operate by a process called negative feedback. Negative feedback helps to maintain stability within a system by detecting changes in a controlled variable and activating mechanisms to counteract those changes. This helps to keep the system within a desired range or setpoint.
The three basic components of every feedback control system are: the sensor (or detector) which measures the system's output, the controller which processes this information and generates a control signal, and the actuator (or final control element) which takes the control signal and adjusts the system's input to achieve the desired output.
Feedback control is the process by which a system's output is monitored and used to adjust the system's input. This mechanism allows the body to regulate internal conditions within a narrow range, maintaining homeostasis. Negative feedback is a common type of control system where the system responds in a way that reduces the discrepancy between the desired and actual output.

Positive feedback tends to magnify a process or increase its output by reinforcing and amplifying the desired behavior or outcome. This can lead to exponential growth or improvement in the system or process.
The main reason for not using feedback control system is that time lag may cause a process deviation near the beginning of a process not to be recognized until the process output. It can result in substantial deviation throughout the entire process, causing an error to continue without adjustment. Since feedback control systems usually take input from one sensor. there may be better and more direct ways to control a system using multiple sensors. Operator intervention is usually required when the system is not able to maintain stable closed-loop control. Feedback control systems do not take predictive control actions for effects of known disturbances.
A BECK controller, often used in process control, operates by continuously monitoring the process variable (PV) and comparing it to a setpoint (SP). It uses a feedback loop to adjust the control output based on the difference, known as the error signal. The controller applies algorithms, such as PID (Proportional-Integral-Derivative), to calculate the necessary adjustments to maintain the desired performance and stability of the system. This ensures that the process remains within the desired operating conditions despite disturbances.
A proportional-integral-derivative controller (PID controller) is a generic control loop feedback mechanism widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly.http://en.wikipedia.org/wiki/PID_controller
