The Answer is Cruise control in a car is a great example of push-pull regulation. The set point in this case is the desired speed that the driver wants to maintain. When the driver activates the cruise control, they set the speed at which they want the car to travel, which becomes the set point for the system.

Negative feedback comes into play when the car's speed deviates from the set point. If the car starts to go faster than the set point, the cruise control system will apply negative feedback by reducing the amount of fuel being sent to the engine, slowing the car down. On the other hand, if the car starts to go slower than the set point, the system will increase the fuel flow to the engine, speeding the car up. This negative feedback loop continuously adjusts the car's speed to keep it as close to the set point as possible.

Positive feedback, on the other hand, is not desirable in this scenario. If the cruise control system were to apply positive feedback, it would increase the car's speed even more when it's already going too fast, or decrease the speed even more when it's already going too slow, leading to an unstable and unsafe driving situation.

The command signal in this case is the input from the driver, telling the cruise control system what speed to maintain. The system then uses negative feedback to continuously adjust the car's speed to match the command signal, keeping it as close to the set point as possible. This push-pull regulation ensures that the car maintains a steady speed, providing a smooth and comfortable driving experience for the driver.
