Title:
PID CONTROL DEVICE AND PID CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/077565
Kind Code:
A1
Abstract:
The present invention is provided with: an elapsed time measurement unit 6 that monitors the temperature T of a control target 1, performs processing to detect the time at which the temperature T of the control target 1 passes a set temperature Tref, and measures an elapsed time tela from the previous passage time until the current passage time; and a remaining time calculation unit 7 that uses the elapsed time tela measured by the elapsed time measurement unit 6 to calculate a remaining time trest until auto-tuning ends. A remaining time display unit 8 displays, on a 7 segment display unit, the remaining time trest calculated by the remaining time calculation unit 7. Due to such a configuration, a user is able to ascertain the remaining time until auto-tuning ends.
