🔍 Key Concepts

• Closed-loop control system basics (how feedback is used) • Meaning of negative feedback in process control • Purpose of an error signal (what two quantities it compares)

💭 Think About

• In a feedback system, what two values are compared to decide whether the system needs to correct its output? • If the system is trying to reduce the difference between actual value and setpoint, what mathematical operation best represents that idea? • Which operation (sum, difference, product, quotient) would tell you not just that the values are related, but whether the actual value is higher or lower than desired?

✅ Before You Answer

• Identify what the setpoint represents and what the measured value represents. • Decide which operation gives both magnitude and direction of the needed correction (too high vs too low). • Eliminate options that would not clearly show whether the process variable is above or below the setpoint.
