Gravity can add some problems in multi-body simscape models: at the beginning of the simulation, some sag will be experience that may be unwanted.

In order to start the simulation at equilibrium, few measured can be employed that are described in this document.

A part of a piezoelectric stack can be used as a force sensor.

Then, the force sensors is collocated with the part of the stack used as an actuator and Integral Force Feedback control strategy can be used to add damping in the system.

This is performed on an Amplified Piezoelectric Actuator
