Can I use 7344 card to control other dynamic system

[dirsing]

Excuse me
I want to control a piezoelectric stripe actuator, I just want to input a step function to the actuator and use the 7344 PID controller to control the actuator.


___________ ________
step input | 7344 | | | step response
--->o--->| PID |--->|actuator|--------->
^ |controller | ---------- |
| ------------ |
|___________________________________|
feedback


Dose 7344 controller satisfy my request?

Thank you

In fact the control algorithm on the 7344 can be used for a variety of control tasks. I have dealt with customers who use the board for controlling force, pressure, piezo stack actuators and piezo ultrasonic motors. As long as your drive provides an analog control input and an appropriate feedback signal (quadrature encoder or analog output) I don't see a reason why the 7344 shouldn't be able to control a piezo stripe actuator.
I don't know much about the characteristics of a piezo stripe actuator but maybe you will have to consider setting the parameters for a static friction deadzone in the 7344 configuration in addition to the normal PID parameters. You need to set these parameters whenever there is a deadzone around the zero voltage output. Refer to this link for further information about deadzone compensation.
