Catch Me If You Can! – Frequency Response of a PID Controller

We all believe that a well tuned PID control loop will reduce process variability… but how do we define process variability?

Variability is composed of slow meandering/drifting disturbances to very fast noise and everything in between. If you attended my last webinar "What the Fourier!" we learned that process variability can be broken down into a broad range of fundamental harmonics. But how effective is a PID controller when confronted with this broadband process variability?

This webinar will explore how effective a PID controller can attenuate process variability – from slow to very fast.
