An error in original version has been corrected, I would like to thank
Torcuato Fernandez for pointing out the error.

How to use

The process is specified by the process gain, time constant and dead time.
The PID controller has 3 parameters: gain, integral and derivative.
Key in these values into the appropriate cells. If the integral time
is keyed in as 0, the integral term is ignored.

The response to a step change in the set point is displayed in the chart.

The screenshot below shows an example of the inputs and the output chart.
