Pneumatic control valve model & system identification

Does anybody did this before? How did you process hysteresis?

Answer 1

[Ryan G]

There are 2 demos available that use a simscape model and a simulink model for a pneumatic system.

For hysterisis you can use something like a backlash.

Thank you Ryan, I do not have simscape. I only have simulink and system identification. Can I still look at these demos?

[Ryan G]

You can look at the Simulink model. The backlash is a simulink based block. If it's not what you want it should at least get you pointed in the right direction.

How can backlash block in simulink be used to model hysteris from real data of control valve ?
