Installation

Implemented code was tested in MATLAB version 2018. No additional installation is needed. Just run one of the main scripts (*.m files in the root directory of the code).

Description of the main MATLAB scripts used in paper

• Algorithm.m

This .m file obtains equations for second-order (five-parameter) process model identification from the characteristics areas (process models). Used in Section 3 of the paper.

• Test_frequency_domain.m

This .m file tests proposed model identification method in the frequency-domain (identification of the model from a general-order transfer function with a time-delay). Used in Section 4.1 of the paper.

• Test_time_domain.m

This .m file tests proposed model identification method in the time-domain (identification from an open-loop time response of a process). Used in Section 4.2 of the paper.
