7.10 PID control

PID control is commonly used to control the procedure. Adjust the output frequency by proportional,
integral, differential operation with the dispersion of the target signals to stabilize the value on the
target. It is possible to apply to the flow, pressure and temperature control. Figure of basic control is
as below:
