TC05 : Tuning Control Loops

TC05 : Tuning Control Loops

  • course description:

    This course is directed to anyone who would like to gain a better understanding of how to tune control loops-whether they have tuned loops but would like to become more proficient or they have never tuned a loop before.

  • course learning outcomes:

    At the end of the course, the participants will be able to;
    - Define the concepts of PID control.
    - Explain the operation of the components in a closed loop control system including static and dynamic functions.
    - Identify the requirements for open loop and closed loop stability.
    - Use three methods to tune a control system for stated quality control.
    - Apply the functions of cascade control loops and the advantage of cascade control over single element feedback control.
    - Tune a cascade control loop for optimum control.
    - Apply the principles and design features of feedforward control.
    - Tune a feedforward control system for optimum control.
    - Identify the advantages of feedforward control over feedback control.
    - Apply the operation and function of ratio control systems.
    - Tune ratio control systems.

  • Course outlines:

    - Review of Feedback Control Concepts and Components: History of Control Operation | Concepts | Pictorial Representation | Disturbances in the Loop.
    - Control Modes: Proportional | Integral | Derivative.
    - Dynamic and Steady State Considerations: Gain | Dead Time | Time Constant.
    - Tuning Control Systems: Closed Loop Tuning Using Ziegler Nichols Method | Evaluation and Control Criteria.
    - Cascade Control: Primary Loop | Secondary Loop | Design and Tuning Criteria.
    - Ratio Control: Applications | Implementation.
    - Feedforward Control: Criteria | Applications | Tuning | Implementation | Material and Energy Balances.
    - Safety Concerns and Procedures when Operating Control Systems.

  • practical aspects of the course:

    Classroom/Laboratory Exercises:
    - Demonstrate the operation of components required for closed loop control.
    - Review start-up procedures for single- and multi-loop systems.
    - Tune feedback control loops via a number of different methods.
    - Tune cascade, ratio, and feedforward control systems.
    - Tune using PC-based simulation software.
    - Observe operation and tuning of a feedback control loop.
    - Tune cascade, ratio, and feedforward control systems using PC-Based simulation software.
    A hand-held calculator should be brought to class.

  • who should attend?

    - Registrants are expected to have a basic understanding of instrumentation and controls (either by working experience or taking fundamental courses such as ISA's FG07: Introduction to Industrial Automation and Control) as this course does not cover that material.
