Title:
PID AUTOMATIC CONTROL METHOD
Document Type and Number:
Japanese Patent JPS5583901
Kind Code:
A
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 gamma and then decides whether the absolute value is smaller than the prescribed value, for example, 2 deg.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.
