Process Control Using a PID Controller

Application ID: 866

This model shows how a flow model can be coupled to a process control mechanism.

Controlling application parameters according to other application parameters is important within process engineering. Most control mechanisms use the data at a wall or an outlet to control inlet parameters. More accurate control can occur if you can control inlet parameters due to data found within a component or piece of equipment.

This model couples mass transfer to fluid flow with two inlets (one controlled) and a PID controller. In this case, fluid flow is controlled according to the concentration at a point within the geometry - therefore a requirement for a physical model.

The model makes use of the PID Controller add-in to implement the PID control.

This model example illustrates applications of this type that would nominally be built using the following products:
