How is the force due to Z piezo motion determined?
Hello, Can you please tell me how the force due the Z piezo motion can be found when the Z piezo motion is arbitrary. In the VEDA manual (http://nanohub.org/resources/15166/download/VEDA_Manual.pdf), this force (referred to as F_i^Z) is determined for the special case when the Z piezo is moving with constant velocity (Eq. 109-110).
This question arises for the case when the Z piezo movement is generated by a PI controller in a feedback loop, as illustrated in Fig. 88 of the same manual.
