Questions and Answers

What does the integral operator do in the described algorithm?

  • Produces an actuator signal based on the history of the previous errors (correct)
  • Acts as a proportional multiplier in a linear way
  • Anticipates the next change based on the slope of the error function
  • Increases the intensity of the signal until it is large enough to be used by the actuator
  • What is the role of the actuator in the context of this algorithm?

  • It increases the intensity of the signal until it is large enough to be used by the actuator
  • It operates as a final control element in contact with the process
  • It produces an actuator signal based on the history of the previous errors
  • It is an electromechanical device that takes the actuation signal and converts it into motion (correct)
  • What is the function of the final control element?

  • Increases the intensity of the signal until it is large enough to be used by the actuator
  • Closes or opens as operated by the actuator to control the flow of a process (correct)
  • Acts as a proportional multiplier in a linear way
  • Produces an actuator signal anticipating the next change based on the slope of the error function
