Process Control

The purpose of this course is to provide the student with a thorough understanding of the various aspects of process control and its application to PLC systems. In addition to open-loop and closed-loop systems, the course also covers advanced closed loop techniques including PID control. Analog I/O devices are presented in detail and tuning parameters for PID control systems is demonstrated through practical examples.

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 function of the setpoint, 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 associated with closed-loop control systems.
  • Define dead time.
  • Explain the basic operating principles of On-Off and PID control.
  • Describe the purpose of feedforward control in process systems.
  • Define the terms algorithm and flowchart.
  • Explain the basic principle of fuzzy logic.
