>> Understanding & Tuning Control Loops

Description :

This course covers the principles of automatic industrial control and the operation of the proportional, integral and derivative control modes. Advanced concepts of cascade, ratio, and feed forward control are presented, as are methods of controller tuning.

You will be able to :

  • Understand the concepts of PID control.
  • Explain the operation of the components in a closed loop control system including static and dynamics functions.
  • Identify the requirements for open loop and closed loop stability.
  • Use three methods to tune a control system for stated quality control.
  • Understand the functions of cascade control loops and the advantage of cascade control over single element feedback control.
  • Tune a feed forward control system for optimum control
  • Identify the advantages of feed forward control over feedback control.

You will cover :

  • Review of Feedback Control Concepts and Components : History/ 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/ Open Loop Tuning/ Evaluation and Control Criteria.
  • Cascade Control : Primary Loop / Secondary Loop / Design and Tuning Criteria.
  • Ratio Control : Applications / Implementation.
  • Feed forward Control : Criteria L Applications / Tuning L Implementation/ Limitations.

Classroom/ Laboratory Exercises :

  • Demonstrate the operation of components required for closed loop control.
  • Review start-up procedures for single and multi-loop systems.
  • Observe operation and tuning of a feedback control loop.
  • Tune multi-loop and feed forward control systems using a PC-Based simulation software.
