“…Based on adding a dual-buck circuit, this topology enables the generation of three voltage levels at the inverter output side. This converter is available in two topologies, and three-leg [52] and four-leg [54] configurations. Figure 23 shows the three-leg configuration.…”

Power electronic devices play an important role in energy conversion. Among the options, matrix converters, in combination with predictive control, represent a good alternative for the power conversion stage. Although several reviews have been undertaken on this topic, they have been conducted in a non-systematic manner, without indicating how the studies considered were chosen. This paper presents results from a systematic literature review on predictive control applied to matrix converters that included 142 primary papers, which were selected after applying a defined protocol with clear inclusion and exclusion criteria. The study provides a detailed classification of predictive control methods and strategies applied to different matrix converter topologies. Research findings require to be understood in combination to develop a common understanding of the topic and ensure that future research effort is based on solid premises. In light of this, this study identifies and characterizes different predictive control techniques and matrix converter topologies through systematic literature review. The results of the review indicate that interest in the area is increasing. A number of open questions in the field are discussed.

“…An LC filter is connected between the input terminals of the rectifier stage and the ac‐source which mitigates high‐order harmonics produced by the commutation of the switches and avoids overvoltages. This is a second‐order model defined as [17], where the more relevant equations are

L_{normalf} \frac{d {bold-italici}_{normals}}{d t} = v_{s} - v_{i} - R_{f} i_{s},

C_{normalf} \frac{d {bold-italicv}_{normali}}{d t} = i_{s} - i_{i} .

The rectifier of the two‐stage converter must always generate a positive dc‐link voltage to ensure the correct operation of the converter and thus avoid any short circuit in the capacitors of the input filter. The voltage in the dc‐link

v_{dc}

is defined by

v_{dc} = T_{normalr} {bold-italicv}_{normali},

with

T_{normalr}

the instantaneous transfer matrix of the input stage defined as

T_{normalr} = (][, S_{r 1} - S_{r 4} S_{r 3} - S_{r 6} S_{r 5} - S_{r 2}) .

The current circulating in the input side of the two‐stage converter are defined by

{bold-italici}_{normali} = T_{r}^{normalT} i_{dc} .

“…This idea has been also extended for 4Leg‐IMCs [17]. A predictive current control strategy with minimisation of the instantaneous reactive power has been proposed for both the classical and three‐level four‐leg IMC, respectively, in [17, 18]. The application of model predictive control (MPC) in 4L‐IMC under unbalanced supply and load conditions has been presented in [19], where the objective has been proposed for dual three‐phase output applications.…”

Model predictive control (MPC) has emerged as a real alternative for the control of different topologies of power converters. In particular, MPC has been successfully applied in matrix converters, significantly reducing the difficulty of control compared with classical techniques. In this study, a predictive voltage control strategy for a four-leg indirect matrix converter is proposed. The idea is based on the discrete minimisation of a cost function in order to select the best vector state of the power converter to be applied in the next sampling instant. Experimental results are presented to validate the proposal under several operating points.

“…In recent years, model predictive control (MPC) has been widely applied in power electronics and power drives because of the fast dynamic response, simple principle and easy implementation, such as three‐phase inverter [6, 7], pulse width modulation (PWM) rectifier [8, 9], matrix converter [10, 11], induction motor drive [12, 13] and PMSM drive [14]. In the traditional MPC, one voltage vector is applied during one sampling period.…”

This study presents a robust three-vector-based low-complexity model predictive current control with supertwistingalgorithm-based second-order sliding-mode observer for permanent magnet synchronous motor (PMSM). First, to reduce the computational complexity of the three-vector-based model predictive current control, the optimal voltage vector combination is directly determined by the sector of desired voltage vector. Second, a supertwisting-algorithm-based second-order sliding-mode observer is designed to observe the lump disturbance caused by model mismatch and unmodelled dynamics. The estimated lump disturbance is considered as the compensation to the original PMSM model to reduce steady-state current error, which improves the robustness of the three-vector-based model predictive current control. Finally, the effectiveness of the proposed method is verified by experiments on a two-level-inverter-fed PMSM drive platform. Experimental results prove that, compared with three-vector-based model predictive current control, the proposed method can reduce the computational complexity and enhance robustness against motor parameters variation.
