Open-loop and closed-loop systems
22 min · IntermediateUnderstand the concept
Open-loop control issues a command without measuring the result. Closed-loop control compares a setpoint with measured output and changes the command based on error. Feedback adds resilience but can create instability.

Your exercise
Draw both versions of a motor-speed control diagram and identify the measured variable.
Practice in simulation or at safe low voltage unless supervised by qualified personnel. Follow official equipment safety guidance.

What makes a system closed-loop?
Practice quizzes are formative and can be retried. Answers are evaluated in your browser; they are not proctored exams.
