Patent Searching and Data


Title:
INFORMATION PROCESSING DEVICE, PROGRAM, AND CALCULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/006332
Kind Code:
A1
Abstract:
Provided is a feature for evaluating, with regard to FRIT, the stability of control in a system having a disturbance compensator. An information processing device (1) calculates a control parameter in a control system (S) of a closed loop system provided with a disturbance compensator (Dw). A time series data acquisition unit (30) acquires first time series data, which is time series data obtained by adding an output of the disturbance compensator (Dw) to an output of a controller (C), and second time series data, which is time series data of an output of a control subject (P). A pseudo-reference signal calculation unit (31) calculates third time series data, which is a pseudo-reference signal of the control system (S), from a first parameter, a second parameter, the first time series data, and the second time series data. A complementary sensitivity function calculation unit (32) calculates a complementary sensitivity function for the controller (C) on the basis of the second time series data and the third time series data. An output operation unit (33) calculates fourth time series data, which is an output when an input signal of the control system (S) is applied to the complementary sensitivity function.
