Process Control

It is in this module that the student learns the principles of industrial control systems including open- and closed-loop control. Proportional, Integral, and Derivative control are covered with an emphasis on practical application and design. PID instructions are described in detail, and an introduction to algorithms and flow charts is also presented in this module.

Learning Outcomes:

Upon completion of this module the student will be able to:

  • Define the terms process, process variable and controlled variable.
  • Name four applications for control systems.
  • Explain the advantage of using block diagrams.
  • Describe the relationship between the set point, error signal and measured value.
  • Differentiate between open-loop control and closed-loop control.
  • List the five basic components in a closed-loop control system.
  • Name the four variables that are generally used to evaluate the performance of a closed-loop control system.
  • Define dead time.
  • Explain the basic operating principles of on off, proportional, integral, derivative and PID control.
  • Describe the purpose of feedforward control in process systems.
