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 based on the existing speed of
the equipment or machinery being controlled. Control maintains
consistent speed or operates at the target speed.
Pressure control Controls pressure by using feedback based on the existing pressure
of the equipment or machinery being controlled. Control maintains
consistent pressure or operates at the target pressure.
Flow control Controls flow by using feedback based on the existing flow in the
equipment or machinery being controlled. Control maintains
consistent flow or operates at a target flow.
Temperature control Controls temperature by using feedback based on the existing
temperature level of the equipment or machinery being controlled.
Control maintains a consistent temperature or operates at a target
termperature.
PID Basic Operation
PID operates by controlling the output frequency of the inverter through automated system
process control to maintain a target (setpoint) speed, pressure, flow, temperature or tension.
