PID Control
Pid control is one of the most common automatic control methods. It uses a combination of
proportional, integral, and differential (PID) control that provides effective control for automated
systems.
The functions of PID control can be applied to the inverter operation for control of the following:
Code 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
ouput to maintain a constant pressure.
Flow Control
Control flow by using feedback of the existing flow comparing
it to a target flow. The inverter adjust 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.
Basic PID Operation
PID operates by controlling the output frequency of the inverter in automated process control
systems to maintain speed, pressure, flow, and temperature.
