6 PID Control Group (PID)
PID control is one of the most common auto-control methods. It uses a combination of
proportional, integral, and differential (PID) controls that provide more effective control for
automated systems. The functions of PID control that can be applied to the inverter operation are
as follows:
Purpose
Function
Speed Control
Control speed by using feedback of the existing speed
comparing it to a target speed. The inverter adjusts the output to
maintain a constant speed (the target speed).
Pressure Control
Control pressure by using feedback of the existing pressure
comparing it to a target pressure. The inverter adjusts the output
to maintain a constant pressure.
Flow Control
Control flow by using feedback of the existing flow comparing it
to a target flow. The inverter adjusts the output to maintain a
constant flow.
Temperature Control
Control temperature by using feedback of the existing
temperature comparing it to a target temperature. The inverter
adjusts the output to maintain a constant temperature.
