If you have a digital proportional, integral, derivative (PID), you can look at the output of each term. You can look at the error input to the PID. If real detail is needed at a specific time, it’s possible to look at the pulse width directly.

The desired setpoint is realized by processing the resulting error signal (or difference between the setpoint and actual value) by a proportional-integral-differential (PID) feedback controller that drives the z-piezo to minimize the error signal.
