Title:
SYSTEM IDENTIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/118736
Kind Code:
A1
Abstract:
This system identification device identifies a linear discrete-time system by means of a recursive method with respect to the dimensions belonging to a specified system dimension search range, calculates as a system characteristic the system output in the case that actual identification input data has been applied to the linear discrete-time system corresponding to each dimension, determines as the system dimension (n) the smallest dimension among the dimensions such that the normal distribution (41) of the sum of the squared error in the time region of the system output and the actual identification output data of a dynamic system is no greater than a threshold (42), and identifies a system matrix of the linear discrete-time system on the basis of a state vector generated using the determined system dimension and the input/output vector of the dynamic system.
