Open-loop systems input and feedback to control a system's functions.

• A. True

• B. False

Use the following passage to match the control system parts to their corresponding element from the passage. While on long road trips, using cruise control to control the speed of the car saves Patrick from driving fatigue. He simply pushes the accelerator to his desired speed, then presses the "set" button. This triggers the system to remember the throttle position and speed then keeps it at that position. The engine recognizes disturbances to the speed, like hills and wind resistance, and adjusts the throttle appropriately to maintain the desired speed.
