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:
Purpose
Function
Speed control
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.
Pressure control
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.
Flow control
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.
Temperature control
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.
5.8.1 PID Basic Operation
PID operates by controlling the output frequency of the inverter, through automated system
process control to maintain speed, pressure, flow, temperature and tension.
