Spurious Response Due to Linear Interpolation of Input Load and Some Remedies

This repository contains the source code and example models of paper 10.1080/13632469.2024.2372814.

To cite or reproduce figures in the paper, you can find the corresponding figure and copy the source code in your work. Please check CI/CD workflow to see how to generate figures used in the paper.

The numerical examples used in the paper are developed in suanPan. To perform the numerical analysis, one can download and install suanPan. Then run the model via, for example, the following command in the corresponding folders under the corresponding folders in MODEL.

suanpan -f Sine.supan

To generate the figures used in the paper, one can create a Python environment and then execute the scripts.
