I have a question regarding Bode diagram. My system is in terms of transfer function in Simulink and would like to see frequency response.
System is a valve, stays in mid position and can make back and forward strokes. The length of stroke depends on the voltage applied. So I would like to see its behaviour against sinus voltages whose amplitude range between 0-9 V.
When I make a normal bode diagram analysis, don´t know what my input amplitude is. Could anyone enlighten me ?
