Feedback concepts are important for many areas of engineering, science and technology. Feedback is the process by which a system measures its own behavior against some standard and uses this information to adjust its future performance. With feedback, it is possible to control complex systems and ensure that they operate according to the desired goals. Here we will discuss two practical applications of feedback concepts: automobile systems and medical sciences.

The most common example of feedback in automobile systems is cruise control, which uses sensors to measure the speed of the car relative to a target speed set by the driver. If the car goes above or below this target speed, it then adjusts its throttle output accordingly in order to maintain a constant speed. This type of feedback loop allows for automated control over vehicle speed without requiring manual intervention from a driver each time they want to change their speed on the road.
