Basically, one PID's (orPI) Control Variable (Output) supplies the next PID's Set Point (Target). I use mostly Rockwell controllers, from your description, use the temperature as your first loop's …

Nov 4, 2005 · A control scheme that measures two variables, where variable #2 biases the PID output calculated on the error between setpoint and variable #1; called feed forward.

Oct 29, 2014 · Multiple process variables can be controlled by automatically adjusting a single output by taking the minimum or maximum output from a PID loop for each process variable.

Jul 11, 2022 · You can use two or more PID’s to control a single CV by using a selection block to create an override control strategy. Basically when one PID is in control the other is initialized …

Dec 14, 2021 · I've got a system that uses two parameters, let's call them F and P, to control the mass flow rate of a substance flowing into a chamber. I need to control the concentration …

For example, to control both the temperature and pressure in an exothermic chemical reaction, you might have a PID loop for temperature, another PID loop for pressure, and use the lesser …

Apr 13, 2021 · I can simply make another PID variable and assign it similar variables and the same tuning parameters as such. PID myPID(&Input1, &Output1, &Setpoint1, Kp, Ki, Kd, …

May 15, 2014 · If you want to do the job right, add a differential pressure transmitter across the control valve and use that as process variable for the VFD PID controller, so you control the …

Dec 30, 2018 · I want to make a PID controller to control the angle of the robot (using a wall as reference) and also its distance to the wall. I made a PID controller that can minimize the …

Oct 17, 2014 · Multiple PVs can be controlled by automatically adjusting a single OP by taking the minimum or maximum OP from a PID loop for each PV. The OP of all loops must be …
