Abstract:
1. A Proportional Integral Derivative adjustment support device comprising: a tolerance interval storing device storing in advance a tolerance interval recognized by a user in regards to target quantity data of a model to be controlled; a modeling result display displaying the target quantity data and, as a modeling result, a model-response waveform that is a control-response waveform that is calculated based on the model to be controlled; a tolerance interval display overlaying and displaying the tolerance interval stored in the tolerance interval storing device and the modeling result; and a time axis corrected tolerance interval processor correcting, in accordance with a display position of the tolerance interval, the tolerance interval for a time axis that is displayed overlaying the modeling result, wherein the time axis corrected tolerance interval processor corrects the tolerance interval for the time axis in accordance with elapsed time on the time axis from a start of control in the target quantity data and the model-response waveform, until the display position of the tolerance interval for the time axis.
