Title: Disturbance suppressing apparatus, disturbance suppressing method, and program
Inventor: YAMAGUCHI SHOHEI
IPC: G05B13/02
Filed: 2019-03-06
Abstract: To provide a disturbance suppressing apparatus capable of highly precisely suppressing a disturbance even if a system fluctuation occurs.SOLUTION: A temperature control apparatus (a disturbance suppressing apparatus) 200 includes: a proportional band information obtaining unit 30; a system fluctuation rate determining unit 35; and a disturbance operation amount correcting unit 40. The proportional band information obtaining unit 30 executes an adjusting process for adjusting control parameters of a PID control unit 15 in accordance with a time period for a control system to obtain information representing a proportional band. The system fluctuation rate determining unit 35 obtains a proportional band change rate between the first proportional band having the information obtained at the first time period and the second proportional band having the information obtained at the second time period later than the first time period, and determines the system fluctuation rate of the control system using the proportional band change rate. The disturbance operation amount correcting unit 40 divides a disturbance operation amount FF1 created by a disturbance operation amount predicting unit 20 for the first time period by the system fluctuation rate to create a disturbance operation amount FF2 for the second time period.SELECTED DRAWING: Figure 2
