Title:
VIRTUAL SENSOR DEVICE FOR FLUID-SOLID SOFT STRUCTURE AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/169025
Kind Code:
A1
Abstract:
The present invention relates to a virtual sensor device for a fluid-solid soft structure and an operation method thereof. The virtual sensor device according to an embodiment comprises: an experiment data acquisition part for acquiring modal data derived through a modal experiment with regard to a fluid-solid soft structure; a physical model update part for updating a physical model for simulating the fluid-solid soft structure by using an order reduction modeling method and the acquired modal data; an actual measurement data measurement part for measuring actual measurement displacement data from a first point of the fluid-solid soft structure; and a virtual sensor information generation part for estimating virtual displacement data at a second point of the fluid-solid soft structure by using the updated physical model, the measured actual measurement displacement data, and a virtual sensing algorithm, and generating virtual sensor information at the second point on the basis of the estimated virtual displacement data.
