Hey Guys,
Got an application where the Engineer purchased some Hydraulic Servo Valves and would like me to write a PID to control the position of the axis the Hydraulics are moving. There is an Absolute rotary encoder hooked up to this rotational axis and the general idea is he'd like to input a position in engineering units and have this things aggressively move towards that position until it gets very close in which it should slow down and stop.
So what's the best way to accomplish this? PID? I've never used it before so some serious help would be needed. The Valve is setup as analog output 8 bit and I have the Encoder as a 0-10v input. They're all working and talking over EtherNet/IP to my CompactLogix PLC.
As usual all help is appreciated.
