🔍 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.

Question 1 of 20

In a closed-loop process control system featuring negative feedback, what is the function of the error detector within the controller?

The error detector computes the product of the measured value of the controlled variable and the desired value (setpoint).

The error detector computes the difference between the measured value of the controlled variable and the desired value (setpoint).

The error detector computes the quotient of the measured value of the controlled variable and the desired value (setpoint).

The error detector computes the sum of the measured value of the controlled variable and the desired value (setpoint).
