11.5 Control Mode Parameters
SuperFlow systems utilize a Proportional, Integral, and Derivative (PID) gain method, hence the
term PID control. SuperFlow provides each system with an initial set of optimized control mode
parameters to provide adequate control for a wide variety of testing applications. The parameters
are:
• Actuator phase
• Controller phase
• Open rate
• Close rate
• P-Gain
• I-Gain
• I-Threshold
• I-Time
• D-Gain
• D-Time
• Filter
• Delay
11.5.1 Actuator Phase
The actuator phase (allowed values: 0 or 1) determines the actuator direction of travel as a
response to the controller output signal. A “1” inverts the signal. If the actuator phase is 0, the
actuator goes from 0 to 100% when the controller output signal goes from 0 to 100%. If the actuator
phase is 1, the actuator goes from 100 to 0% when the controller output signal goes from 0 to 100%.
The actuator phase must be correctly selected to properly drive the control mechanism on the
dyno system.
