7.15 PID control
PID control is commonly used to control the procedure through the controlled 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:
