Cascade control of hydraulic actuator


Thread Starter


Hi there,

I am right now working on an electrohydraulic cascade control concept of proportional valves. It is mostly a theoretical work. Just wanted to ask if anyone in this forum have experience with such an approach. I didnt write it detailed since whoever worked with this, would understand what i mean.

Thanks in advance,
If you are talking about an electrohydraulic valve that has multiple stages and can be used for proportional control then I believe Parker, or one of the other hydraulic valve companies has one. If memory serves, it could be set up to accept 0-10 V and 4-20 ma inputs, and translate them into 0 to 15 discrete valving steps.
