Course Number: TC05
Length: 2 days
Cost: $2,045 (Cdn Dollars)
Synopsis
This two day course covers the principles of automatic industrial control and the operation of the proportional, integral and derivative control modes. Controller tuning is also covered.
Objectives
- Understand 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.
- Understand 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.
- Understand the principles and design features of feedforward control.
- Identify the advantages of feedforward control over feedback control.
