Abstract
PURPOSE: To make it possible to stabilize a controlling variable and controlled variable in a short time by exercising proportional-differential-integral control when a deviation of a measured temperature from a set temperature is below a fixed value or by exercising ON-OFF control when above the fixed value.
CONSTITUTION: When a deviation a measured temperature measured by temperature sensor 12 from a set temperature is below a fixed value, solenoid 15 of four- mouth solenoid valve 14 stays unexcited and a heating fluid supplied from conduit 18 is led into heat exchanger 19 under the control of automatic valve 17 to exercise proportional-differential-integral PID control over a heat source. On the other hand, the deviation of the measured temperature from the set temperature is above the fixed value, the deviation is detected by temperature regulator 13 to excite four- mouth solenoid valve 14, and consequently while automatic valve 15 is fully opened, an air-pressure signal PID-controlled is led out from four-way solenoid valve 14. As a result, when the temperature deviation decreased below the fixed value, automatic valve 15 is placed in an unexcited state and the PID control system is in effect under ON-OFF control. Consequently, a controlling variable and controlled variable can be stabilized in a short time.
