Interval Robust Controller to Minimize Oscillations Effects Caused by Constant Power Load in a DC Multi-Converter Buck-Buck System
Kevin Eduardo Lucas Marcillo,Douglas Antonio Plaza Guingla,Walter Barra,Renan Landau Paiva de Medeiros,Erick Melo Rocha,David Alejandro Vaca Benavides,Fabricio Gonzalez Nogueira +6 more
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.
Journal ArticleDOI
Novel Robust Methodology for Controller Design Aiming to Ensure DC Microgrid Stability Under CPL Power Variation
Kevin Eduardo Lucas-Marcillo,Douglas Antonio Plaza Guingla,Walter Barra,Renan Landau Paiva de Medeiros,Erick Melo Rocha,David Alejandro Vaca-Benavides,Sara Judith Rios Orellana,Efrén Vinicio Herrera Muentes +7 more
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.
Proceedings ArticleDOI
A 3D vision based approach for optimal grasp of vacuum grippers
TL;DR: This paper aims to estimate the best picking place for a two suction cups vacuum gripper, when planar objects with an unknown size and geometry are considered, in such a way that minimizes the vacuum force needed to guarantee a grasp.
Proceedings ArticleDOI
Parameter Optimization of an Interval Robust Controller of a Buck Converter Subject to Parametric Uncertainties
Kevin Eduardo Lucas Marcillo,Douglas Antonio Plaza Guingla,Erick Melo Rocha,Walter Barra,David Alejandro Vaca Benavides,Renan Landau Paiva de Medeiros +5 more
TL;DR: The results show that the optimized interval robust controller is able to maintain acceptable performance across the operating range, with a minor performance degradation compared to an intervals robust controller and a conventional controller.
Journal ArticleDOI
Multivariable Fractional Order PI Autotuning Method for Heterogeneous Dynamic Systems
Ricardo Alfredo Cajo Diaz,Cristina I. Muresan,Clara-Mihaela Ionescu,Robain De Keyser,Douglas Antonio Plaza Guingla +4 more
TL;DR: The proposed robust Fractional Order Proportional-Integral autotuning control strategy is presented and applied to heterogeneous dynamic systems using decentralized control and its performance is compared against two other fractional order controllers based on PI gain-crossover autotuned method and Internal Model Control.
