PID Tuner gives you several ways to adjust the plant parameters:
- Graphically adjust the response of the estimated system by dragging the adjustors on
the plot. In this example, drag the red x to adjust the estimated plant time constant.
PID Tuner recalculates system parameters as you do so. As you change the estimated
system’s response, it becomes apparent that there is some time delay between the
application of the step input at t = 5 s, and the response of the system to that step
input.
To add a transport delay to the estimated plant model, in the Plant Structure section,
check Delay. A vertical line appears on the plot, indicating the current value of the
delay. Drag the line left or right to change the delay, and make further adjustments to
the system response by dragging the red x.- Adjust the numerical values of system parameters such as gains, time constants, and
time delays. To numerically adjust the values of system parameters, click Edit
