🔍 Key Concepts

• Closed-loop control system vs open-loop control • How a system uses the difference between setpoint (desired value) and process variable (actual value) • The basic idea of feedback in automatic control

💭 Think About

• In a closed-loop system, what must the controller know in order to correct the output? Think about how it compares actual vs desired values. • Which of these terms describes a signal that is sent back to influence the input of the system based on its output? • Which options refer to specific problems or characteristics (like too little response or too much response) rather than the basic correcting mechanism itself?

✅ Before You Answer

• Identify which choice describes using the error (difference between desired and actual) to make corrections. • Eliminate any terms that mainly describe problems or limits in a control system rather than its normal correcting action. • Confirm which term is fundamental to automatic correction in closed-loop control systems.
