Thank you all for the helpful posts! I know it's basic stuff, but when you lack basic intuition, basic's the best info you can get. Also thanks for the link to examples of valve-solenoid-joystick kits! Cheers :)
Hahaha. Thanks! Sorry for the show of ignorance. I've dealt more with robotic systems with automatic control systems and I guess I extrapolated to construction machines, about which I clearly don't know much.
The human provides the PID using a joystick or lever or some other mechanism, and...
Natchwey, where can I find more info on control design for elevators and their regulations? I've been wondering how they work and would love to know more. I am not about to design one, rest assured :D
Thanks!
I'm modeling a few construction machines for simulation and I need to know how the actuators are normally controlled. Are PID controllers typical---in backhoes, excavators, and aerial lifts, say? How do they keep the actuators stable against loads without constantly adjusting the force produced...
