Hydraulic Engineer give the Acceleration of theoretical calculations. It=1000mm/s

The actual process of debugging，More than 500 ，the position trace is not good。

I want to know the Relationship of theoretical calculations and actual good control Acceleration.

e.g.

theoretical calculations=1000, calculations and actual good control Acceleration is the 1/2 heoretical calculation? or else

Your question does not have enough detail to be answered. The definition of “theoretical” is the problem. “Theoretical” usually refers to the results of calculations done with some model. A model, by definition, is not perfect. The question is how accurate the model is. Any system can be modeled in many different ways. For a model that is not very good, maybe the acceleration can only be half of what the model says. For a good model, maybe the acceleration can be the same as the model says.
