Questions & Step-by-Step Solutions

Which of the following describes a closed-loop control system?
  • Step 1: Understand what a control system is. A control system is a way to manage or regulate a process or system.
  • Step 2: Learn about the two types of control systems: open-loop and closed-loop.
  • Step 3: Know that a closed-loop control system uses feedback. This means it checks the output of the system.
  • Step 4: Understand that feedback is the information about the output that is sent back to the system.
  • Step 5: Realize that the system compares the output with the desired input (what you want it to be).
  • Step 6: Learn that if there is a difference between the output and the desired input, the system makes adjustments to correct it.
