“…As shown in Figure 5a, the 3L-NPC-VSI has a total of 27 basic switching states vectors. When synthesizing virtual vectors, the basic voltage vectors which generate a CMV exceeding Vdc/6 are not used [27]. Therefore, the small virtual vector VVS1 and VVS2 constructed by three adjacent small basic vectors with a low CMV (CMV ≤ Vdc/6) can be expressed as: In OMR-II, if the θ satisfies 0 ≤ θ ≤ α h or π/3 − α h ≤ θ ≤ π/3, the reference voltage vector will locate in the holding region, otherwise in the equivalent region.…”

“…Shaft voltage and bearing current will be generated by the common-mode voltage (CMV), which may destroy the motor insulation in motor drive applications and increase the leakage current in the distributed generation applications [22][23][24][25]. Virtual space vector PWM (VSVPWM) provides a new idea for the NP voltage control and the CMV suppression [26][27][28][29][30][31][32][33]. A novel VSVPWM considering NP voltage balance and CMV suppression is proposed in [23].…”

The three-level neutral-point clamped voltage source inverter (3L-NPC-VSI) is widely used in the maglev traction systems due to its high output voltage, large output capacity and low output current harmonics. In order to improve the utilization of the DC-bus voltage, an overmodulation strategy is necessary. This paper proposes an improved overmodulation strategy based on the minimum amplitude error method for a 3L-NPC-VSI. Compared with the conventional overmodulation strategy based on the minimum amplitude error method, the utilization of the DC-bus voltage is higher. Meanwhile, a virtual space vector modulation strategy is adopted for inverter neutral-point (NP) voltage balance and common-mode voltage (CMV) suppression. Furthermore, the suppression of leakage current also has been verified. Furthermore, the implementation details of the proposed overmodulation strategy based on minimum amplitude error method is elaborated. The effectiveness of the proposed method is verified by simulation and experimental results.

“…Nevertheless, the application of non-adjacent VVs causes high voltage dv/dt, which are correlated to the switching devices voltage stress and electromagnetic interferences. In [23] MPC is adopted for CMV suppression for a Linear Permanent Magnet Synchronous Motor (LPMSM) drive fed by a Neutral Point Clamped Inverter (NPCI) where redundant VVs with higher CMVs are discarded. In [24] authors exploit the FCS-MPC to dynamically adjust the number of candidate vectors according to the predicted current ripple.…”

In this work, a novel multi-objective voltage-vectorbased finite control set model predictive control for a permanent magnet synchronous machine drive fed by a three-phase five-level cascaded H-bridge multilevel inverter is proposed. This algorithm aims to overcome the main issues relative to model predictive control implementation detected in the scientific literature for electric drives fed by cascaded H-bridge multilevel inverters. In detail, the goals are the minimization of computational cost by reducing the number of required predictions, the minimization of the switching devices state transitions, i.e. the switching losses minimization, and the common mode voltage reduction. These goals are fulfilled through an offline optimization process, thus, no additional terms and weighting factors to be tuned are required for the cost function. Experimental validations are presented to prove the effectiveness of the proposed approach. In detail, an accurate electric drive performance comparison, both in steady state and dynamic working conditions, is carried out when the proposed voltage-vector-based model predictive control and the cell-by-cell-based model predictive control are adopted. As comparison tools, current and voltage total harmonic distortion, apparent switching frequency, common mode voltage amplitude, and torque ripple are adopted.

“…At present, the main control strategy is predictive control [7], [8], Model-free control [9]- [11], PI control, and adaptive control [12]. Literature [13] applied predictive control to the PMSLM control system to improve the speed controller, ensure the strong robustness of the linear motor system, and reduce the speed fluctuation. Many control methods have been proposed, such as active disturbance rejection control (ADRC), model-free adaptive control (MFAC), and MFC.…”

To simplify the system structure of permanent magnet synchronous linear motor (PMSLM), optimize the kinematic performance of the control system, and further improve the speed tracking accuracy of PMSLM, a model-free speed regulation system design of PMSLM based on the adaptive observer is proposed. Aiming at the control instability problem caused by the parameter uncertainty of PI control in PMSLM, a model-free speed controller (MFC) based on the ultra-local model is proposed, which has strong robustness to the uncertainty of motor parameters. Meanwhile, the actual model of PMSLM is used to build the reference model of the adaptive observer, and the adjustable model is designed with the current equation of PMSLM, to identify the speed of PMSLM. The design not only reduces the dependence of the speed controller on the motor parameters, but also simplifies the complexity and cost of the control system, and improves the control performance and anti-interference ability of the control system. The MFC and the observer based on the model reference adaptive system (MRAS) are built by simulation software and applied to the PMSLM system to verify the superiority of the designed control system. Compared with PI controller, sliding mode controller (SMC), and sliding mode observer (SMO), this control method not only simplifies the control system in structure, but also improves the accuracy of PMSLM tracking speed, improves the dynamic response performance of PMSM control system, and optimizes the control ability of the control system.
