Amplifier Piezoelectric Actuator APA300ML - Test Bench
Table of Contents
The goal of this test bench is to extract all the important parameters of the Amplified Piezoelectric Actuator APA300ML.
This include:
- Stroke
- Stiffness
- Hysteresis
- Gain from \(V_a\) to \(d\) (in [m/V]), then it should be possible to compute the gain from \(V_a\) to \(F_a\) using the Simscape model
- Gain from \(\delta L\) to \(V_s\) (in [V/m])
