Remote Setpointgreenspun.com : LUSENET : PID Controller Tuning : One Thread
With a PID-controller I want to control the pressure in an installation for hig-pressure-cleaning.
The Sauer-Danfoss hydraulic pump, which drives te HP-pump, has an electrical displacement control which controls the swashplate angle of S-D Series 90 Pump.
It must be possible that the desired pressure is set from a distance with a joystick/turn button/remote control. This value serves as setpoint in the controller and can change during the proces according to the pressure the user of the installation wants.
Can anyone give me a good plc-brand, which have these feature in it? thanks.
