Abstract
PURPOSE: To decrease the overshoot and increase the transient response properties by adding the integrating member when the measured value enters the prescribed range of the set value.
CONSTITUTION: Control unit 4 obtains the difference, i.e., deviation e between measured value C and set value γ and then decides whether the absolute value is smaller than the prescribed value, for example, 2°C. And only when the absolute value is smaller than the prescribed value, the integrating member is added. Then operation amount m is obtained based on the PID control formula. The signal corresponding to the operation amount is sent to driving circuit 5 to control heater 2.
