The PID Loop Simulator comes with flow, level, temperature, custom and signal generator inputs. It is a great tool for instructors and students alike, and it is a perfect companion to any PID tuning course or text. You do not have to take my word for it, though; you can try it now!
Use the flow, level, and temperature simulators to teach or study PID tuning techniques. Use the custom simulator to design your own process response, pH titration for example. Use your nonlinear creation to demonstrate the importance of multiple bump tests, or to teach linearization techniques. Finally, use the signal generator to study or demonstrate each tuning parameterís response to process offset (error) and process rate of change.
I could post pretty screenshots of PID Loop Simulator here, but why should I? You can see the application in action! Give it a try; then purchase it risk free. Install it on your computer(s). If you are not completely satisfied, request a refund within one month and I will refund 100% of your money.
