TL;DR: An interval robust controller, by linear programming based on Kharitonov rectangle, is proposed to regulate the output of source converter, which shows the effectiveness of the proposed controller when the multi-converter buck–buck system is subjected to a variation of power reference.

TL;DR: A novel robust controller is presented, based on linear programming based on the Chebyshev theorem as a robust control technique considering the Kharitonov's theorem that ensures the minimization of the total deviation from the desired performance in a closed-loop system, specified by a family of characteristic polynomials.

TL;DR: The design and evaluation of robust controllers are presented, based on linear programming, Kharitonov's theorem and Chebyshev's theorem, in order to enhance the performance of a typical structure of multistage converters present in direct current (dc) systems.

TL;DR: Old systems aiming to provide the well-known advantages of Industry 4.0 to such legacy systems as reducing production costs, increasing efficiency, acquiring better robustness of equipment, and reaching advanced process connectivity are upgraded.

TL;DR: The experimental results show that the proposed methodology can maintain a desirable performance even in the presence of parametric uncertainties, and the performance indexes calculated from experimental data show that it outperforms classical MIMO control techniques.
