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.

nComponents have long working life resulting in longer system reliability nEnvironmentally friendly nSafety issues are minimized e.g.. Fire hazards; unaffected by overloads (actuators stall or slip) pneumatic actuators in a system do not produce heat (except for friction)
It is called feedback because it is regulated by its own product. In other words, the product of the reaction gives a feedback which either inhibits the reaction (negative feedback) or activates it even more (positive feedback).
i will put tank ckt and give it to transistor via positive feedback
By using C-filter
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.

advantages and disadvantages of using a formal feedback system?
The concept of feedback in cybernetics originated with Norbert Wiener in the 1940s. It refers to the process of using information about the output of a system to regulate and control the input, creating a closed-loop system. Feedback mechanisms are essential for maintaining stability and making adjustments in response to changes in the environment.
By using your brain
Feedback systems are those that regulate a state or action by receiving controlling inputs that are primary or secondary outputs from the process the system intends to regulate. A good example of a negative feedback control system is the thermostat in your house.

Light intensity can be controlled by adjusting the power input to the light source, by using a dimmer switch or a variable resistor. Another way to control light intensity is by using filters or shades to reduce the amount of light emitted. Advanced techniques include using a feedback system that automatically adjusts the light intensity based on environmental conditions.
