1. The output of the measurement device is the . a. measured variable b. feedback signal /c. neither a or b 2. Which elements and signals of a control system do not exist in an open-loop configuration? a. comparator b. error signal c. measurement device d. feedback signal e. all of the above 3. An error signal develops when which of the following conditions occur? a. the set point is changed b. a disturbance appears c. the load demand varies d. all of the above 4. The is the difference between the condition of the controlled variable and the set point. a. measured variable b. feedback signal c. error signal d. disturbance 5. A is an example of an unintentional factor that causes the condition of the controlled variable to become different from the set point. a. set point change b. disturbance c. load change d. Feedback Change 6. is the elapsed time between the instant a deviation of the controlled variable occurs, and the corrective action begins. a. Time lag b. Dynamic response c. Dead time d. Pure lag 7 a. reedtorward control takes corrective action after a disturbance occurs. b. Feedback c. Open-Loop 8. The automatic control of process operations is performed by a. open-loop systems b. closed-loop systems . c. both \( a \) and \( b \) d. None 9. The set point typically remains unchanged in a a. motion b. process control system
