Tuning software is supposed to simplify the process of improving the control of individual PID loops. And while that’s the expectation most tuning products can’t handle the noisy, oscillatory conditions that are commonplace in industrial applications. What’s even more absurd is that those products require users to hold their processes steady before the software can begin to function properly. The irony for most practitioners is that PID tuning software isn’t needed if a steady-state can be established – they can tune their loops manually.
