One Click to Simulation, Modeling, Frequency and Robustness

March 3, 1995 -- ExperTune PID Tuner for Windows now includes simulation,
modeling, robustness and frequency response of your plant loop by
selecting "Analysis".

The user first runs ExperTune's AutoTune sequence, then selects Analysis
and four powerful windows appear:

- Modeling - select one of 4 model types, up to second order with
  dead time.
- Frequency response - showing both actual and model for easy
  comparison.
- Robustness plot - available only with ExperTune - quickly show the
  tradeoff between tuning and stability.
- Simulation - lets you try "what if" analysis off-line - see the
  response of your process before you download tuning. Set point or
  load response.

The windows are completely automatic, integrated and cohesive. Select a
different model, and the simulation, frequency and robustness plots
instantly update. Change PID tuning selection or enter in your own PID
values and the simulation and robustness plots instantly update to show
you the simulated effect on your loop before you download.
