Requirements: View

The Simple PID Demo VI lets you see how a PID control system works without needing an external system to actually control. Run the VI. Notice with the default values you have a classic first order system reacting to a square wave. Try changing the System Type to 2nd ORDER and notice that the Process Variable does not track the Set Point very well. Try setting P=10, I=6, and D=5. Notice the difference as you tune the system. You can experiment with different Set Point Types and tuning parameters to get a feel for tuning systems. View the Context Help window description of each control for more information about its use.
