Title:
LOAD IDENTIFICATION METHOD AND SYSTEM BASED ON HYBRID ITERATIVE REGULARIZATION
Document Type and Number:
WIPO Patent Application WO/2023/246117
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of load identification. Provided are a load identification method and system based on hybrid iterative regularization. The method comprises: performing TSVD on a Green kernel function transfer matrix, and dividing decomposed singular values into a larger singular value and a smaller singular value, wherein the larger singular value is a singular value greater than a set value, and the smaller singular value is a singular value less than or equal to the set value; correcting the smaller singular value by using a Gaussian high-pass filtering function as a regularization matrix for Tikhonov regularization, so as to obtain a TSVD-Tikhonov-Gaussian hybrid regularization result; and solving the TSVD-Tikhonov-Gaussian hybrid regularization result by using an LSQR algorithm, thereby realizing more accurate identification of different types of loads.
