Title:
PID CONTROL DEVICE AND PID CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/106782
Kind Code:
A1
Abstract:
Provided is a PID control device with a startup tuning function to calculate PID parameters used for PID control of an object to be controlled before starting the PID control. The PID control device is provided with: a velocity change measuring unit for measuring a velocity change in temperature of the object to be controlled; and a level division determining unit for determining boundaries of levels of the PID control that uses the calculated PID parameters, on the basis of response characteristics of the velocity change in temperature as measured by the velocity change measuring unit.
