What is the key difference between an open-loop control system and a closed-loop control system?

  • A closed-loop system uses an IP-enabled controller whereas an open-loop system does not.
  • A closed-loop system uses a negative feedback mechanism whereas an open-loop system uses a positive feedback system.
  • A closed-loop system uses a feedback mechanism whereas an open-loop system does not.
  • A closed-loop system uses a controller whereas an open-loop system does not.

Explanation: A closed-loop control system uses feedback to determine if the output is the desired output and makes adjustments if necessary. An open-loop control system does not use feedback. Both closed-loop and open-loop control systems use a controller, standalone or with a network connection.
