A method to control the output current of a three-phase grid-tied inverter is presented. An LCL-filter is used to reduce the current distortion injected into the grid. The objective is to minimise current distortion and switching frequency to reduce losses. The control approach is based on finite control set model predictive control with sphere decoding to make the problem computationally tractable for long horizons. A mathematical model was derived that extends on previous work by incorporating the effect of a grid-voltage to the system. The control strategy was evaluated through simulation. The results indicate that this control strategy can achieve the objectives for its application mentioned in the paper.

In this paper a predictive control technique for an indirect matrix converter is proposed. The control strategy allows the output current control and the instantaneous reactive input power minimization of the converter without any weighting factor in the controller and, at the same time, the operation at fixed switching frequency. Simulation results validate the proposal under both steady and transient states.

This paper proposes a predictive control technique for an indirect matrix converter. The proposed control strategy gives sinusoidal waveforms at both the input and output of the converter without any weighting factor in the cost function and, at the same time, giving operation at a fixed switching frequency. Simulation results with an unbalanced ac-supply validate the proposed method under both steady state and transient conditions.

In this paper a predictive control technique for an indirect matrix converter is proposed. The control strategy allows to impose a sinusoidal waveform in both the input and output current of the converter without any weighting factor in the controller and, at the same time, the operation at fixed switching frequency. Simulation results validate the proposal under both steady and transient states which are also compared with the predictive current control strategy with minimization of the reactive input power.

This study proposes a finite-state model predictive controller to regulate the load current and balance the DC-link capacitor voltages of a four-leg neutral-point-clamped converter. The discrete-time model of the converter, DC-link, inductive filter, and load is used to predict the future behavior of the load currents and the DC-link capacitor voltages for all possible switching states. The switching state that minimizes the cost function is selected and directly applied to the converter. The cost function is defined to minimize the error between the predicted load currents and their references, as well as to balance the DC-link capacitor voltages. Moreover, the current regulation performance is improved by using a two-step prediction horizon. The feasibility of the proposed predictive control scheme for different references and loads is verified through real-time implementation on the basis of dSPACEDS1103.

This paper presents a direct model predictive control (MPC) strategy for the quasi-Z-source inverter connected to a linear/nonlinear load via an intermediate LC filter. The proposed scheme simultaneously controls the ac-side output voltage and the dc-side capacitor voltage and inductor current. The discrete-time model of the converter is derived which can be used for both modes of operations, namely the buck and boost mode. Evaluation results are presented to highlight the performance of the proposed strategy.

A predictive control algorithm specially developed for shunt active power filters aimed to compensate reactive power and current harmonics components is presented and analyzed. The proposed predictive control algorithm is implemented in a three-phase four-leg voltage-source inverter (4L-VSI). The use of a 4L-VSI allows the compensation of current harmonics, reactive power and neutral current harmonics generated by single-phase non-linear loads. A detailed mathematical model of the filter, including the effect of the power system equivalent impedance is derived and used to design the proposed predictive control algorithm. The proposed active power filter and associated control scheme performance and compensation effectiveness are demonstrated by simulation and with experimental results.
