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
How elevator work open loop or close loop?
Elevators typically operate using a closed-loop control system. In this system, sensors continuously monitor the elevator's position and speed, providing real-time feedback to the control system. This allows for precise adjustments to be made to ensure smooth and accurate operation, responding to user inputs and safety requirements. In contrast, an open-loop system would lack this feedback mechanism, making it less effective for applications like elevators where precision is crucial.
How do you generate control signals?
Control signals are generated through a combination of algorithms and hardware components, typically within a control system. These signals are created using feedback from sensors that monitor system states, which are processed by controllers (like PID controllers) to determine the appropriate output. The output is then transformed into control signals that can actuate devices or systems to maintain desired performance or stability. In digital systems, microcontrollers or processors are often employed to execute these tasks through programmed instructions.
What is the function of a control circuit?
A control circuit regulates the operation of electrical systems by managing the flow of current and signals between various components. It ensures that devices operate within specified parameters, enabling automation and precise control of processes. By using inputs from sensors and feedback mechanisms, a control circuit can adjust outputs to maintain desired performance levels and enhance system efficiency. Overall, it plays a crucial role in various applications, from industrial machinery to household appliances.

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 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.
