Title:
CONTROL DEVICE ADJUSTMENT ASSISTANCE DEVICE AND CONTROL DEVICE ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/193678
Kind Code:
A1
Abstract:
The present invention identifies a parameter and an adjustment direction for the parameter with respect to an adjustment target for a PID control device. A control device adjustment assistance device (10) assists with adjustment of each parameter of a proportional element, an integral element and a differential element of a PID control device (20). A notification unit (12) outputs a parameter adjustment guide in a form detectable by a user. A waveform measurement unit (11): derives a first ratio between the phase difference of the proportional output and the differential output of the PID control device and a quarter cycle of the proportional output or the differential output; causes the notification unit to output a parameter adjustment guide indicating that the differential element is strong if the first ratio is less than a predetermined first threshold value; causes the notification unit to output a parameter adjustment guide indicating the proportional element is strong if the first ratio is at least the predetermined first threshold value and not greater than a predetermined second threshold value; and causes the notification unit to output a parameter adjustment guide indicating the proportional element is weak or the integral element is strong if the first ratio is greater than the predetermined second threshold value.
