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.

∙ 15y agoThe thermostat, which is connected to the a/c and heat system, has Mercury in it that is encased in a glass tube. As the temp gets warmer, the weight of the mercury expands and causes it to move to the opposite end of the tube, which in turn causes contacts to close on the unit, which then turns the unit on. As it cools down, it moves back to the other end of the tube, and the reverse occurs, shutting the unit off. If you have the unit in the heat mode, then it is the opposite, and closes a different set of contacts.

Is a thermostat an example of positive or negative feedback?
Negative feedback is a reaction that causes a decrease in function. Using a thermostat, it senses the temperature of an area and responds by either turning on or off the heater or air conditioner.
What reason might a farmer have for using biological control instead of chemical pesticides?
what reason might a farmer have for using bioligical control instead of chemical pesticides
How do organisms control their pH levels?
By using buffer systems
What is the importance of knowing the frequency response of an instrument when making bio measurements?
what specific you are trying to measure ?. you said Bio measurements ?can you be specific, and what instrument you are using, what parameter you want to measure, once I know this I should be able to answer.Rickwww.calculatoredge.comnow calculations made easy!
How is biogical control and how can you use it for pest?
That would be not using any chemicals or bug sprays. Biological pest control consists of using a natural predator to eradicate the problem pest. Like turning ladybugs loose on a bush that is infested with aphids.
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 do you introduce feedback circuit in dc motor speed control?
By using your brain
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).
What is a reason for not using feedback control system?
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 does your body maintain though negative feedback?
Your body maintains homeostasis through negative feedback. This somewhat like using a thermostat to maintain a narrow range of temperature in the house.
What are measuring devices?
measuring devices different according to the parameter you want to measure. weight is measure using weighing balance temperature is measure using a thermometer, or thermistor. length is measured using ruler. and so on
