Ziegler-Nichols Loop Tuning
This protocol is designed to optimize the loops for disturbance rejection.
There is the possibility for the loop to go unstable at too high gain. Use caution as gain is increased. |
- From the Home Screen, touch the Channel icon for the loop to be tuned
- Touch Settings > PID Params
- Choose a Set Point temperature
- Set Proportional Gain (KP) to 0
- Turn off Integral and Differential portions of the loop (TI & TD, respectively)
- While monitoring the error in temperature on rolling graph, slowly increase KP until the error begins to oscillate
- Note KP where oscillation begins, KP, cr
- Use the following table to set the values of KP, TI, and TD
