“…OSS-MPC has the highest computational cost since it allows the vector used for the switch control to be obtained. However, the use of an inter-sample-based cost function improves the steady state response and reduces the output THD when compared with the other techniques [17,27]. This is justified by the fact that the switching frequency is constant owing to the SVM modulation scheme used.…”

This research paper studies and highlights the features of the most popular finite control set model predictive control (FCS-MPC) strategies available in the state of the art, which are the optimal switching vector (OSV-MPC), modulated model predictive control (M2PC), and optimal switching sequence (OSS-MPC) methods. Thus, these strategies are studied experimentally by analyzing the transient and steady state performance using a grid tie conventional three-phase two-level voltage source inverter (VSI) with inductive output filter in a Typhoon HIL real-time simulator (RTS) with a Texas Instruments F28379D digital signal processor (DSP). Hence, quantitative indicators, such as the maximum tracking error, the mean absolute error, the settling time, the total harmonic distortion, the switching frequency spectrum, the switching pattern, and the computational burden are compared with the aim to deduce the best strategy for each criteria.

“…A previous FCS-MPC comparison paper [16] compared four different techniques; however, it did not compare the most recent one, which is the OSS-MPC. Another comparison research paper [17] studied the same three techniques of this research paper. However, both papers only presented Matlab ® /Simulink simulation results.…”

“…However, as a disadvantage, this class presents a variable switching frequency. Nevertheless, some studies aim to minimize the frequency harmonic spectrum dispersion by incorporating specific goals into the cost function [38,39]. Power electronics-based systems have as their main characteristic the finite number of switching states, so in power electronics converters, the control action is limited to the set of switching states possible in the converter, making the MPC an option that is feasible and easy to implement.…”

Model-Based Predictive Control with Graph Theory Approach Applied to Multilevel Back-to-Back Cascaded H-Bridge Converters

The multilevel back-to-back cascaded H-bridge converter (CHB-B2B) presents a significantly reduced components per level in comparison to other classical back-to-back multilevel topologies. However, this advantage cannot be fulfilled because of the several internal short circuits presented in the CHB-B2B when a conventional PWM modulation is applied. To solve this issue, a powerful math tool known as graph theory emerges as a solution for defining the converter switching matrix to be used with an appropriate control strategy, such as the model-based predictive control (MPC). Therefore, this research paper proposes a MPC with the graph theory approach applied to CHB-B2B which capable of not only eliminating the short circuit stages, but also exploring all the switching states remaining without losing the converter controllability and power quality. To demonstrate the proposed strategy applicability, the MPC with graph theory approach is tested in four different types of SST configurations, input-parallel output-parallel (IPOP), input-parallel output series (IPOS), input-series output-parallel (ISOP), and input-series output series (ISOS), attending distribution grids with different voltage and power levels. Real-time experimental results obtained in a hardware-in-the-loop (HIL) platform demonstrate the proposed strategy’s effectiveness, such as DC-link voltages regulation, multilevel voltage synthesis, and currents with reduced harmonic content.
