“…The model given by (17)-(18) is an exact discrete-time model, in the sense that the continuous-time state and output (12)- (13) are exactly recovered at the k-th sampling instant, where y k = y(kT s ) and x k = x(kT s ). However, for nonlinear or time-varying models (as in the case of the IM) exact discrete-time models may be hard or impossible to obtain explicitly since this requires to compute the matrices of (17)-(18) online.…”

System modeling and variables estimation are two important task in direct control strategies. In those schemes, the system performance is strongly related with the accuracy of the discrete-time model, especially for time-varying systems, e.g., high-performance motor drive applications. This investigation presents a numerical comparison between several discrete-time models of the induction machine (IM) used in model predictive control (MPC) schemes. The accuracy of each model is evaluated numerically for different speed operation points. The results serve as a preliminary validation to select an accurate discretization method for MPC drive applications.

“…Another example of a PWM strategy, aimed at CMV reduction, this time in an asymmetrical sixphase drive with a single neutral point, is described in [17]. The idea of [18] is however very different and it is suggested to incorporate a criterion related to the CMV as a part of the cost function that is used in conjunction with model predictive control (MPC) based current controllers. Correlation between carrier-based PWM and space vector PWM for two-level multiphase inverters has been explored in detail in [19].…”

AbstractMultiphase variable-speed drives and generation systems (systems with more than three phases) have become one of the mainstream research areas during the last decade. The main driving forces are the specific applications, predominantly related to the green agenda, such as electric and hybrid electric vehicles, locomotive traction, ship propulsion, 'more-electric' aircraft, remote offshore wind farms for electric energy generation, and general high-power industrial applications. As a result, produced body of significant work is substantial, making it impossible to review all the major developments in a single paper. This paper therefore surveys the recent progress in two specific areas associated with multiphase systems, namely power electronic supply control and innovative ways of using the additional degrees of freedom in multiphase machines for various nontraditional purposes.Index TermsMultiphase variable-speed drives, ac-ac converters, inverters, PWM, multiphase power electronics, integrated on-board battery chargers.

“…Common-mode voltages generated by fast switching operation in three-phase VSIs are also known to cause overvoltage stress on the winding insulation of drives and radiate electromagnetic interference noise, which can affect the functionality of other electronic systems in the vicinity [3]. Given that zero-voltage vectors lead to the highest common-mode voltage, studies on alleviating the common-mode voltage by avoiding the zero vectors in PWM blocks have been conducted [3]- [8].…”

A model predictive current control (MPCC) method that does not employ a cost function is proposed. The MPCC method can decrease common-mode voltages in loads fed by three-phase voltage-source inverters. Only non-zero-voltage vectors are considered as finite control elements to regulate load currents and decrease common-mode voltages. Furthermore, the three-phase future reference voltage vector is calculated on the basis of an inverse dynamics model, and the location of the one-step future voltage vector is determined at every sampling period. Given this location, a non-zero optimal future voltage vector is directly determined without repeatedly calculating the cost values obtained by each voltage vector through a cost function. Without utilizing the zero-voltage vectors, the proposed MPCC method can restrict the common-mode voltage within ± V dc /6, whereas the common-mode voltages of the conventional MPCC method vary within ± V dc /2. The performance of the proposed method with the reduced common-mode voltage and no cost function is evaluated in terms of the total harmonic distortions and current errors of the load currents. Simulation and experimental results are presented to verify the effectiveness of the proposed method operated without a cost function, which can reduce the common-mode voltage.
