RESUMO:

This work has as its main contribution the design and development of a predictivecontrollers applied to a single-phase H bridge inverter connected to the grid using LC filter.Simulations are used to validate the proposed control strategy. The main contributions ofthe work are: (I) Mathematical modeling of a single-phase inverter with LC filter for theapplication of predictive control; (II) Development of predictive algorithms based on FiniteControl Set model with variable and fixed; (III) Comparison of the proposed predictivecontroller in relation to a controllers: PI adjusted appropriately by the frequency responsemethod and P+RES with the same PI proportional gain, with integral gain and resonancefrequency adjusted empirically. Both controls are applied to a model of a single-phaseinverter with LC filter connected to the grid developed in the Matlab®/Simulink®software.This work has as its main contribution the development and improvement of a predictivecontrol based on a mathematical model of the type by finite states with the use of frequencymodulation applied to the current control of a single-phase inverter with H bridge connectedto the power grid using a filter LC. Simulations are used to validate the proposed controlstrategy. The main contributions of the work are: (I) Mathematical modeling of a single-phase inverter with LC filter for the application of predictive control; (II) Developmentof predictive algorithms based on a Finite Control Set model with variable and fixedfrequency with modulation for the application of 2 and 3 vectors; (III) Comparison of theproposed predictive controllers in relation to the controllers: PI adjusted appropriately bythe frequency response method and P + RES with the same proportional gain as the PI,with integral gain and resonance frequency empirically adjusted. All controls are appliedto the same single-phase inverter model with LC filter connected to the mains developedin the Matlab®/ Simulink®software.
