This paper proposes a model predictive control for a hybrid transformer (HT) with matrix converter (MC). The proposed HT system is composed of a power transformer connected to a power electronic converter which controls the output voltage on the secondary side. The proposed solution of HT is used to resolve power quality issues and power flow control in the electrical power distribution system. The advantages of predictive control are its very simple realization and the possibility to optimize various predefined criteria. Presented in the paperr is a discussion of the conception of a model predictive control strategy to compensate for voltage sags, swells and harmonics on the grid side by providing continuous AC voltage regulation of the HT. Also, presented are the preliminary simulation results, which verify the high performance of the proposed predictive control.

“…The other control strategy is the model predictive control (MPC), which has been applied to inverters and MCs for power supply applications [12][13][14][15][16]. However, employing MPC to control a 400 Hz GPU still remains a challenge due to the insufficient ratio between the switching frequency and the output frequency, as well as the instability caused by the input filter.…”

“…As an example, in [14][15][16], the finite control set model predictive control (FCS-MPC) was successfully used to control the output voltage with a unity input power factor (PF). However, the source current was not fully controlled, and the resultant source currents were distorted.…”

This paper deals with the design, control, and implementation of a three-phase ac–ac mobile utility power supply using a matrix converter for airplane servicing applications. Using a matrix converter as a compact direct ac-to-ac converter can provide savings in terms of the size and cost of a mobile power supply compared to common back-to-back converters. Furthermore, using the proposed direct matrix converter eliminates the need for bulky electrolytic capacitors and increases the system’s reliability and lifetime. A finite control set model predictive control is used to generate a high-quality 115 V/400 Hz output voltage and a low-harmonic-distortion source current with a unity input power factor for various load conditions, including balanced, unbalanced, linear, and nonlinear loads. The predictive strategy is used to control the output voltage and source current for each possible switching state in order to simultaneously track the references. To achieve a further reduction in the system’s size and cost, an active damping strategy is used to compensate for the instability caused by the input filter in contrast to the passive method. Experimental tests were conducted on a prototype matrix converter to validate the performance of the proposed control strategy.

“…Despite their improved control performance, these approaches impose complications and extra calculations to the control platform and might not be suitable for practical applications. Some leading strategies like model predictive control (MPC) have been newly proposed in order to simplify the control of MCs and provide fast and satisfactory performance in both transient and steady states [20–46].

Matrix converters are a well-known class of direct AC-AC power converter topologies that can be used in applications, where compact volume and low weight are necessary. For good performance, special attention should be paid to the control scheme used for these converters. The model predictive control strategy is a promising, straightforward and flexible choice for controlling various different matrix converter topologies. This work provides a comprehensive study and detailed classification of several predictive control methods and techniques, discussing special capabilities they each add to the operation and control scheme for different matrix converter topologies. This study also considers the issues regarding the implementation of model predictive control strategies for matrix converters. This survey and comparison are intended to be a useful guide for solving the related drawbacks of each topology and to enable the application of this control scheme for matrix converters in practical applications.
