SYSTEM IDENTIFICATION DEVICE, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND SYSTEM IDENTIFICATION METHOD

摘要

A data acquisition unit (1) acquires input data and output data of a system to be identified. A memory unit (2) stores initial binary/ternary structure matrices obtained from prior knowledge. A binary/ternary structure matrix generation unit (3) reads the initial binary matrices from the memory unit and generates a plurality of sets of candidate binary matrices. A binary structure matrix selection unit (4) selects one set of binary matrices from the sets of candidate binary matrices. A determination unit (5) determines matrices used in a state equation for the system to be identified and matrices used in an output equation for the system to be identified in response to the selected set of binary matrices. An evaluation unit (6) evaluates whether the determined matrices are reasonable for identifying the system to be identified.
