How to use
The PI controller is specified by the controller gain (C) and the
integral time (TI). The first order process without time
delay is specified by the process gain (K) and lag time (T).
Key in values of K, T, C and TI into the cells B5, B6, B9 and B10 respectively. The step response is displayed in the chart. The max time is to be entered into the cells B13.
See this example screen for the step response with the following inputs:
K = 2
T = 5
C = 1
TI = 0.1
