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.

What are the effects of feedback on time constant of control systems?
1.feedback in control system improves the speed of response2.using feedback in control system we can reduce the sensitivity of the system to parameter variation
What are the benefits of pneumatic control system?
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)
Why do you use feedback in an electrical circuit?
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).

Can you control voltage fluctuations by using capacitor?
By using C-filter
It is a control system that uses feedback from the process to maitain an output to a desired level?
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.

What is formal feedback?
advantages and disadvantages of using a formal feedback system?
How is the concept of feedback originated from the cybernatic?
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.
How do you introduce feedback circuit in dc motor speed control?
By using your brain
How feedback control works using temperature as a control parameter?
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.

How do you control light intensity?
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.
