'Application of Fuzzy Decision Making to the Switching State Selection in the Predictive Control of a Direct Matrix Converter' de los autores Felipe Villarroel, José Espinoza y Claudio Molina de la U. de Concepción, en conjunto con Christian Rojas y José Rodríguez de la U. Técnica Federico Santa María.
Resumen: The finite states model predictive control is a promising alternative in the field of the control of power converters. Its characteristics allow simple and flexible control schemes with
fast dynamics. However, the standard formulation of this type of controllers, which is based on an aggregated cost function, requires suitable weighting factors for an adequate switching
state selection. The specification of these factors depend on various parameters making it a non trivial process. In this work, an alternative is proposed that replaces the standard aggregated
cost function with a fuzzy decision making strategy. This strategy retains the multiple attribute nature of the state selection. As a result, the possibility of a more natural and higher level design approach to the state selection process is opened. To introduce the technique, only objectives with equal importance are considered. Simulation results are presented to illustrate and validate the approach using the control of output and input currents in the Direct Matrix Converter.
'Discrete Nonlinear Control based on a Double dq Transform of a Multi-Cell UPQC' de los autores Jaime Rohten, José Espinoza, Javier Muñoz, Pedro Melín y Eduardo Espinosa .
Resumen: A Discrete Nonlinear Control with a double dq Transform of a Multi-Cell Unified Power Quality Conditioner (UPQC) based on Single-Phase Power Cells is presented. The UPQC is a back-to-back connection of active filters; combining a shunt and a series topology but maintaining the features of both units, where the main objective is to improve the power quality. The multivariable, nonlinear and coupled nature of the UPQC makes the control a difficult task. In this work a discrete nonlinear control of a multilevel UPQC based on Single-Phase power cells is proposed, where the controlled variables are decoupled to improve both dynamic and static system responses. In this scheme, two different Park Transforms are used to conveniently synchronize each compensator, in order to allow a dedicated control for every output variable. This paper shows that the DC link voltage of every power cell can be controlled in a wider range as compared to a traditional control strategy, thus improving robustness for several types of loads.
