How to use

The PI controller is specified by the controller gain (C) and the integral time (TI). The integrating process has only one parameter T.

Key in values of T, C and TI into the cells 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:

T = 4

C = 1
TI = 1
