5.8 PID Control
Pid control is one of the most common auto-control methods. It uses a combination of
proportional, integral, and differential (PID) control that provides more effective control for
automated systems. The functions of PID control that can be applied to the inverter
operation are as follows:
Controls speed by using feedback about the existing speed level
of the equipment or machinery to be controlled. Control maintains
consistent speed or operates at the target speed.
Controls pressure by using feedback about the existing pressure
level of the equipment or machinery to be controlled. Control
maintains consistent pressure or operates at the target pressure.
Controls flow by using feedback about the amount of existing flow
in the equipment or machinery to be controlled. Control maintains
consistent flow or operates at a target flow.
Controls temperature by using feedback about the existing
temperature level of the equipment or machinery to be controlled.
Control maintains a consistent temperature or operates at a target
termperature.
