Introduction   ignore

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])
