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:
Code 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.
