9-16 PID Controller Functional Block
Go back to the LonMaker tool to configure the PID. Right-click the PID Controller
functional block and select Configure from the shortcut menu. Enter the PID
coefficients using the PID coefficients tab as shown below.
A cascade arrangement is where an outer PID controller’s control variable is used
to drive the setpoint of an inner PID controller. The inner controller must react
strongly to changes in its setpoint.
To make the PID controller react strongly to changes in setpoint, check
Cascade –
even if a cascaded PID is not being used. Normally, precise tracking of setpoint
changes is less important that good tracking across process disturbances.
Cascade
is unchecked in this example.
An increase in the I-term gives less action. An increase in the D-term gives more
action. A controller with more action will react more strongly to a given error.
