“…In order to prevent a computational delay, present in the experimental process, it is necessary to establish the prediction in the step (k + 2) to compensate for the delay and, consequently, apply in (k + 1) the predicted switching state [29], [32], [36], [38], [39]. In this case, assuming that e g (k + 1) = e g (k) for a small sampling time T s .…”

“…As the M 2 PC tests two adjacent vectors in each sampling cycle, the cost function is calculated for each vector. See [36] for more details on the cost function and calculation of duty cycles. After obtaining the duty cycles, the switching states are obtained by comparing the duty cycle with two high-frequency triangular carrier signals.…”

“…This paper discusses an AC-DC-AC single-phase to threephase system with two rectifiers in parallel and the M 2 PC control strategy previously presented in [36]. Two control strategies using the M 2 PC are presented, which are based on the Space Vector Modulation (SVM), the first using a onedimensional plane and the second using a vector plane.…”

“…Also, experimental results validate the predictive control performance applied to the system. In summary, the main contributions of this paper compared with [36] are as follows: I) Proposing a new strategy using the M 2 PC based on the vector plan. In this way, it is possible to obtain a reduction in execution time of approximately 58.76% when compared with the strategy presented in [36]; II) Design to tune the gains of the Proportional-Integral (PI) based on a DC-link voltage controller; III) Regarding the proposed strategy, due to redundant vector four different switching sequences were evaluated and compared;…”

This paper presents a parallel single-phase to three-phase drive system, using two single-phase rectifiers. The rectifiers are not isolated from the grid by low-frequency transformers, so the reduction of the circulation current is an important objective for the control strategy. Modulated Model Predictive Control regulates the grid current and minimizes the circulation current between the parallel rectifiers. Furthermore, the analyzed predictive control consists of two strategies, where the first has the application of two vectors in a sampling period while the second has three vectors. The addition of a vector allows the reduction of the computational cost due to the reduction of tests performed in the predictive control and reduces the harmonic distortion in the electrical grid due to the greater application of vectors in a sampling period. Simulation and experimental results are presented in order to validate the control strategy.

“…Although naturally commutated ac-ac converters have been previously proposed as a compact alternative [3], they exhibit significantly adverse power quality performance. Some topologies for 1φ-3φ static power converters are discussed in [4], [5], [6], [7], however, these have sizeable interdispersed energy storage elements and/or higher device count when compared to the topology considered here. This article proposes the use of 1φ-3φ ac-ac matrix converter (MC) for driving a three-phase induction motor from a single-phase supply [8].…”

This article presents an alternative ac-ac converter topology and its control for low-speed three-phase induction motor drives fed from single-phase ac mains. The proposed matrix converter based drive system eliminates the dc link capacitor, thus facilitating high power density and system reliability. The primary challenge in controlling a 1φ to 3φ matrix converter is to navigate the discrepancy of instantaneous power across the 1φ grid and 3φ load via a direct ac-ac converter. In order to address this concern, it is proposed to use mathematical modeling of the motor and input LC filter for state selection, in order to deliver improved current waveforms. Enhanced performance is demonstrated through simulations, and further validated using experimental results. Particularly improved power quality performance is achieved at low motor speeds, where precise low-speed sensorless operation is ensured through suitable speed observer.
